First you should call some sign places around your area using good ol' yellow pages. Also see if they would like to sponsor you. If thats too expensive try going to a good hobby store and pic up so vinyl grafics without design cut outs. It will be a solid color or design without stickers them selves, and cut em out tracing a pattern drawn on. Or they have vinyl graphics printers that cut out the design just like a printer. One last thing just use spry paint.
