Go to several of your paint supply dealers in your area. Ask them this same question you posted here. There are many of us that did it on the side and Im sure they could set you up. Usually someone that does it on the side will let you prep the car to save some money. Like removing bumpers,chrome,lights,mirrors ect. You could also ask the painters at some shops if they would reccomend someone. I got a lot of my work from friends that only do collision work.
