How to become a wash partner.

This maybe a crazy idea and I'm not shure if it's worth the effort. But I'm wanting to get some experience in being a wash partner. Can't afford to own a wash (Sad face). But at the SCWA (Southwest Car Wash Association) convention, is it possible to advertise that I'm intrested in becoming a partner? If possible there is a location I've been looking at for years. Busy intersection, close to auto-dealers, no other washes for miles, close to some gas stations, no houses near by that might get annoyed by the noisy blowers.
