How do i get sponsors for my Jeep?

[Kile]

I was told by a friend that there are websites that have links to all sorts of company willing to give you free stuff just by slapping their sticker on your car, and advertising for them. I know stuff like this is real, but ive only found one website for this, and it was for like street racing cars... any suggestions? I drive a lifted Jeep Cherokee, so im hooping to find some off road type sponsors
