My Aunt owns one, I worked for her there for about 2 years. They had drop off's where people would pay to have the wash done for them. That's how TF and I got to meet. He was the only guy who didn't have shit stains.
They charge by the pound I think $.85 a pound. Good luck with it and if I can help any way hit me up on ICQ.
IMO it's a great $$ maker.
