Maybe a car magnet also?

As far as bandit signs or car magnets I could see that going either way. 

With 6000 pieces I spend $4680.Doing it myself, including magnets, costs about $3,000; without magnets it's about $2,000.

Most guys with pickups and magnetic signs don't have insurance, heck, they may not have a license!

Pick up the phone and start making some cold calls.Buy a magnetic sign for your car.

I never had my car wrapped - I used to have a magnetic sign on my car.

Business cards and car magnets are not very expensive - use them to let everyone know that you are in this business.

I now only do bandit sings and I am getting solid leads calling me every week. 100 bandit signs a week guarantee you will have leads calling you. btw after 6 month of having a car magnet I did not get a single lead. 

Another way that might help you are magnetic car signs.
