I did my own a few years ago. Want to get a good compressor (at least a 7hp 175psi w/30gal tank), good HVLP guns and a good airbrush and start doing bikes on the side (racebikes mainly at first for practice). There is a guy around here that dos helmets, HD's and such. Theres a guy who I worked with at Geneva Vans who airbrushes helmets damn good. His names Chris and lives somewhere near Antioch area is all I know. I dont remember his last name though.
Well if going up to Rockford is ok then there is a guy with a T-shirt shop in the Cherry Valley mall. Had my tank done there. Very respectable pricing and just ask the guys here, he did an excellent job. Dont have any pics here at home, but will post one tommorrow from work.
