Joe, If you want a "concourse" quality job, then it would be best to go to someone who specializes in this type of work for a living and understands what you want. You will pay big bucks, but get a top notch job. Your average body and paint shop will not want to put the time in to give you this kind of work. Not that I am knocking the average shops, but they can make a lot more "quick" money doing smaller "insurance" type jobs. You will get a cheaper price, but dont expect "top notch" work. Just my opinion.
