AM I WAY OFF BASE ?

Ive been doing body & paint for some time now. From doing small patch work to full quarters, floors you name it. I had a guy wanting me to write up a price for his brother to remove & replace both quarters, outter wheel wells, trunk floor, trunk extensions & all door hinges. Not to mention take out rear & front windows that are already broke. I gave him a price of $3,000 That's labor & materials to do the job. Replacing all factory seam sealer & doing any body work to the quarters. He looked at me like I had two heads & then said o that's with you buying all the body parts. I said no I don't think so. He came back with 'well we will probably just send it to AMD & have them do it' Am I way off base with my price or is he just being a cheap *** ?
