I own a Repo company and we charge $1.30 a mile one way for mileage other charges may apply according to situation. There is a local guy here who does the same thing, I think he also gets the triple A and Harley Owners Group etc etc. He came out to our Charity bike Show and gave out cards pens etc he also does flyers at the local shops and restaurants. The biggest downside that you are missing here is thats this is not an 8 to 5 or an after work thing this is drop what your doing RIGHT NOW AND COME GET ME! Whether you are at work or home in bed asleep.
As a RepoMan I have to be able to get into cars. Thats not a problem. I got to looking and found out that POP A LOCK lock out guys were making around $45 per call. I figured I could beat that with no sweat maybe $30 or $35 but then I figured out the same thing drop what you are doing and come get me in my car right now! If you don't well you've lost more than just one sale. So that is another thing to keep in mind they might all or even any be convient after work jaunts. The next thing is what about insurance? IE basically there are 2 things to consider here
#1 the DOT says that ANYTHING you move for compensation is Freight
#2 if you are moving VEHICLES for a fee you are TOWING and therefore must carry tow insurance
So theoretically you either would have to be insured as a freight carrier or as a tow company, this would probably nullify any profits instantly.
The thing that I must impress on you is this:
#1 Your moving someones motorcycle to a shop for them, a UNINSURED drunk runs the redlight and T bones you destroying the bike. AS SOON AS YOUR Insurance company finds out your were getting paid to move it they will NOT pay for it because you DIDN"T have commercial coverage.
#2 It's YOUR fault you scratched a $35,000 trailer Queen when you were strapping it down, ouch! thats gonna cost you!
#3 It's NOT your fault the guys just a butt and he wants YOU to pay for a scratch you DIDN'T do, what now?
I'm certainly not trying to discourage you from this endeavor just to make sure you are aware of what you may be getting into. Find out if the other guy listed above has Tow insurance if he does and you don't he might file a complaint. How would you advertise? The area tow companies might see the ad and take offense and file a complaint. As a general rule I think this is a wide open untapped market and I think the Austin Area has plenty of call for a knowledgeable careful MOTORCYCLIST to move other Motorcyclists bikes because someone with the same passion and interests will show a higher level of care and safety than Joe Bob Tow Truck Driver just do your research first
