Earn Money from your car

If you own a car, you have a built-in advertising machine on your hands. Just like taxi cabs, you can contract with local companies to display their advertising on your vehicle. Let the potential customer know how much you drive every day, and where, and how many eyeballs they can expect to see their advertising. Now, you're not going to make a fortune with this, but if you're willing to cover your entire car with a company's logos and display ads, you should be able to make $100 a month or so. It's also possible to extend this business even further by arranging with a bunch of car owners who are willing to wrap their cars in a particular company's advertisements.

With this added strength of numbers, you can approach businesses with a more attractive offer. You can put their ads on, say 100 cars, for $5,000 a month. By setting up the deal, you keep half. If that sounds expensive, keep in mind that a single billboard can cost more than $5,000 a month, while 100 different cars would probably expose 3-4 times as many people to the company's message (and in a more novel way) than a simple billboard would. You'll have to have all your facts right before pitching this idea, but it's worth considering.
