got doors back from body-shop

[1968GMC]

I got my doors back yesterday and they look awsome BUT cost me way to much. He coted me $500 for the pair. When all said and done it cost me $850. He did a real nice job dont get me wrong, sanding them down to the metal and such but he told me he spent 40 hours on them( he thought it would take 15 hours). In my opinion, if you are a professional, you should take in to account that you might run in to problems esspecialy on 30 year doors dont you sall agree?Im just venting. Ho BTW that is not eavan painted for that price just primed.
