#86: What is a Side Hustle and Why Does a Private Investigator Need One? P.I. Podcast #59

Most people haven’t heard the term side hustle and it is a term I only learned about a few years ago.  It’s not a bad word and has nothing to do with illegal activity.  I have no intentions of steering you in that direction. 

What is a side hustle?

Entrepreneur.com defined a side hustle as this, “A side hustle is a way to make some extra cash that allows you flexibility to pursue what you’re most interested in. It can also be your true passion – a chance to delve into fashion, travel or whatever it is you care about the most without quitting your day job”.

I like their definition but my definition would be this: A second job you can enjoy (or not) that can be considered a fall back job if your investigation career doesn’t go as planned.  You can grow your side hustle job if needed or have it be a supplement income when times are slow in the private investigation field.

Do all private investigators need to have a side hustle?

The answer in my opinion is yes and no.

Yes because some investigation companies are very seasonal for both self-employed private investigators and for those employed with an investigation company.

It doesn’t hurt to have a hobby that brings in money when your main form of income (main hustle) is slow.  Self employed private investigators or business owners don’t have the option of filing for unemployment when work is slow.  Having a side hustle gives investigators the piece of mind that if things do get slow the side hustle will help pay the bills until things get back to normal.

No because there are plenty of investigator with a business of their own that does very well.

Do I have a side hustle?

Yes I have a side hustle.  Blogging is my side hustle.  I have more than one blog that I write for and I can work on it during my free time (when I have it).  It’s not an overnight thing where you start blogging and make a ton of money, plus it takes awhile to build a following on each blog.

I have had the most fun writing for the P.I. Advice Blog over the years and that is probably why I have created so many videos and podcasts for the blog.

From 2016 to 2017 I have had a couple more side hustles I have been a part of which I think could be possible for anyone to do in the United States while working as a private investigator.


I believe it was the end of August 2016 when my wife and I thought it might be fun to be Scentsy consultants and work together.  Frankly I had always wanted to do some kind of business with my wife.  She isn’t that keen on being anything other then my editor for my blogs and she was mildly interested in being a Scentsy consultant with me.

Scentsy is a wickless candle that melts in decorative candle warmers.  They make like a bagillion different scents and make a variety of different warmers.  

Scentsy can be financially rewarding but it takes quite a bit of work to build up clients.  It requires having many Scentsy parties and being at different events to promote the Scentsy brand.  My sister in law earns $1,500 a month after being into it for 4 years part time.  She has a full time job and only does Scentsy as a part time thing.

As I write this it was decided that we take a break from Scentsy as we just don’t have the time to invest into it at the moment.  It is a lot of fun and you get to meet a lot of interesting people.  I had a great deal of fun doing this with my wife.  I made a little review website that is a work in progress as I had aspirations of making it a marketing funnel but it will have to be put on hold.  

Here is a video I made for one of the scents. Just having fun and exploring some ideas with Scentsy.  

Uber and Uber Eats

Uber (if you haven’t already heard of it) is a ride sharing company.  If you become an Uber driver you are basically a vehicle for hire (kind of like a cab driver) and you pick up people and take them where they want to go.  You can be a driver whenever you want and stop working whenever you want (as long as you don’t have any passengers).  

I have noticed many private investigators turn to Uber driving to fill in the hours during slow periods.  Drivers can potentially average $20 to $30 an hour depending on the time of day.  One friend of mine who is also a private investigator worked 2 hours recently and earned $100 just the other day.  He admitted that was not the usual amount he would make in a two hour period but on that day he took someone to the airport and that was a big fare.  I am not saying every day as a driver is earning $50 dollars an hour but it always has the potential to be.  

I recently started working as an Uber Eats driver on my free time.  An Uber Eats driver picks up food from a restaurant and delivers it to a customer.  It doesn’t pay quite as well as an Uber driver but I am basically guaranteed to work in my city and the surrounding cities and I can start and stop anytime.  

So if you have either Uber or Uber Eats in your area you should consider it when thinking of something to do when work is slow.

Do I know anyone else that has a side hustle and is a private investigator?

Of course I do.  I have worked with many private investigators over the years.  Many of them have hobbies they make money from to supplement their income (because they don’t make enough) and others have a side job that just adds to their income (because they just want more money).

What side hustles have I come across over the years?

Side hustle

Fish Tank Maker

One investigator I worked with learned how to make fish tanks.  He then started buying supplies to make tanks and made side job out of it.  He really enjoyed having a fish tank and it was a great paying hobby for him.  It wasn’t going to pay all of his bills but it was something to bring in some money when times were slow.


This investigator was an author and enjoyed writing.  When I first met him he was writing a book though I never saw it.

Ebay Flipper – Stock Trader – This guy hustled

A friend of mine is an Ebay Flipper.  He purchases things from the Good Will and garage sales and flips the items for a profit on Ebay.  He has actually done pretty well for himself over the years.

The same guy also traded stocks for awhile and made a little money doing that as well.

Side hustle


I have friends that enjoy hunting in the Northwest.  One friend in particular almost matched his full time income as a private investigator by starting a Taxidermist business. He specializes in a particular type of taxidermy and has built up a clientele and has made a decent additional living.  He doesn’t need the extra money but it helps pay for his hunting and fishing toys.

Website Builder/ T-Shirt Designer

This guy was the ultimate side hustler.  He made more money with his side hustles than he did working for a company as a private investigator (and he was a pretty decent private investigator).

He built websites for small companies who didn’t have a website to represent their business. Sometimes he did it for money and other times he did it as a trade.  One time in particular he built a website for a guy who sold custom knives and received some pretty cool custom knives as payment.

When he told me about his T-Shirt design side hustle I was jealous.  He made designs for an online company that printed things on shirts, cups, pens, etc…  He made so much money from his designs at one point he almost retired from the investigation business.

When did he find time to do all this stuff?  When he wasn’t following or videotaping someone on surveillance he was creating all this stuff on his computer while in his car.

Work a Second Job

It might not be something you love or a hobby that pays money.  If you are a private investigation business owner you might want to consider working part time for an investigation company to fill in any gaps or slow times in your business.  Companies are always looking for experience competent investigators.   It might not pay the same but you will have money coming in.

One More Thing

As a Business Owner

You can always just focus on and build your private investigation business to a point where you don’t have to worry about slow times.  There is nothing wrong with that and I hope everyone can have a successful business.

The reality with this industry is that many go out of business quickly because it can be difficult to just build it up to a point where it pays the bills consistently.

As an Employee

Something I have observed about investigation companies is that they frown on investigators that apply for unemployment during slow times in business.  I have seen this to be true with small investigation companies.

A side hustle might keep you from having to go the unemployment route.  And if your side hustle is your passion then you will be more likely to make it be a successful form of additional income.

I hope this has inspired you in some way to start your own side hustle.  If you already have one or plan on starting one I would love to hear about it in the comments below or message me through the contact page.



  1. Interesting topic and yes I do have another hobby that pays. I’ve always enjoyed working on cars; specifically detailing my own vehicles. Since work has been a bit slow with my employer (I’m an SIU Investigator for G4S), I detail 1-3 cars on the weekends for an extra $200 to $600 per week. These are the more expensive vehicles on the road, not your typical Fords, Chevy or Toyotas.

    Hope your summer has been good Andrew!

    • Awesome :). That is a pretty cool side hustle. A very good paying side hustle I must say! Thanks for sharing Brian!

  2. I’m about to get my own company license. My side hustle is similiar to the P.I. work. I do freelance general research on topics and other types of research that can be done online. I’m on a couple of freelance websites like oDesk and Freelancer.

    Great article and great advice for all investigators.

  3. I’m a retired NYPD Detective. I started my next career as a PI for assorted firms, I am currently a government contractor .PI work is going to be my side hustle. What drove me away from PI work initially was unscrupulous and greedy owners .I had a guy owe me 3 grand and he went out of business because he couldn’t make his payroll.
    Your podcast is very informative I’m on episode 22. Keep up the good work !
    PS I’m gonna try Audible.

    • Pat there are some really scummy PI firms out there and it is tough to find a good one to work for. If you work for someone again make sure you interview them just as much as they interview you. Make sure it is a good fit.

      Glad you like the podcast Pat!
