go with the paint, but ask to see the guys work before you let him do it, also monitor him to make sure he isnt slapping gallons of bondo in your baby, if he messes up, get rid of him, its to much work to fix that crap, as far as the line x they way way over quoted you, get in good with the guys down there and you can get a discount, they dont have 100 bucks in materials for your whole truck, i would wait untill the line x guys need work then offer them 300 just for the bed, bargain with people man all they can say is no, but dont lowball them or you will insult them
