I'm going through the same fucking deal.
One shop quoted me $2500 to do both sides, cab corners and all 4 of my door seams. Not sure if that included blending the paint from cab corner to ext. cab door.
Different shop yesterday quoted me $3,000 for both sides, and the price would go up from there to do the door seams and blend the ext. cab doors because they're replacing the cab corners.
I need more quotes, but my passenger front fender needs replacing also. I might as well do the fucking drivers side fender as well before that one pops. Thinking about all this gives me a headache...
