Well first off thanks and every area is different on prices. I would check as many body shops as you can. Basically once there tinted your gonna wanna clear them with auto clear coat. I would say I could do yours but I don't think you live close and your not gonna wanna have your car sitting there while there being shipped. Lol plus it's risky to ship tail/headlights.
Well I did five coats on the trim and three on the rest. I didn't want them to dark just not so bright as stock. I would recommend u going and try to find a junk tail light and practice on it. That way you will see how it applies and how dark it will be.
