Ask for sponsership,Explian the caliber of the events you are entering and the amount of spectators that would be there ,Tell them of the possibilty of magazine photos ,Every second contractor owns a 4x ute it would be exellent exposure for there company to have there stickers on Your flexi yella banana.
You may be suprised its not a big outlay for them,You may come up with a good sponser relationship. Be Polite and don't guzzle beer while your talking to them hehe.
Good luck!
