Cost of a single-color paint job?

The original question (and intent) referred to a single color paint job; in my case, a metallic with clear coat. Specifically, Winchester gray (Gunmetal). All my prep work, including pre-painting of door jambs, under hood and trunk area would be done, car would be sanded and prepped. But it sounds like I'm still looking at more than $2500.00, and for that price I would probably attempt to shoot it myself. I shot the last Duster, but it was a solid (red) with no clear coat. If the experts out there think a metallic with clear coat is too much for an amateur I might have to re-think my game plan and go with a solid.
