Well dont go to the dealership cuz they will let it down like 400, but im figuring the only thing you have to worry bout is the paint job the installation is rather easy. So just find a good paint shop at a good price.
yeah you could take it to a paint shop if there the least bit reputable they will be have the Ford Red to mix. The whole thing shouldn't cost you more than $50-100 depending on the shop and labor costs. For example, I had my rear fascia painted for $120 at a local shop so the scoop should cost near to nothing
