1500-15000, you have to be specific on what you want. Color changes are more..how many coats of clear, or are you even using base clear. Will you prep the car, or will they..list goes on and on. A GOOD paint job for one person would leave another pulling there hair out. For me a good paint job was four coats primer, block sanded after each, two coats color, three coats clear, and finish with wet sanding (20hours). Total cost if I had not participated in the process would have been anywhere from 6-10 thousand depending on the shop. Know exactly what you want from the guy before he starts..and know exactly what he's capable of by looking at his work both done and in process. Get a set price going in, and get a couple compeditive quotes from respected shops..this is one area where most often you get exactly what you pay for.
