Cost of Paint and Bodywork?!

My Dart was nearly rust free. The painter found a few pinholes from the vinyl top, easy fix. It had a few door dings and stuff that needed repaired. It's almost ready for paint.

I am buying all materials myself. He tells me what he needs/wants. He is charging me $3k labor. I disassembled the car myself and will reassemble it myself. I paid ~$550 for the door jambs, window channels, bottom of the hood and trunk, trunk gutter, etc to be sand blasted. He quoted a month and a half to do the while job. It's been 11 1/2 months so far.

We didn't discuss the inner doors above and below the door panels or any of the interior metal. That will cost me extra.
