I put an ad on Craig's List. "Free wall space for graffiti artists" I'll supply the paint, pizza, and beer. I bought nice charcoal filter masks for everyone too. I had like 20 people want to do it so I picked the best 6 and ended up hiring one permanently. It was a great experience. They were all so cool and polite.
