I think Shine is a little short on materials.
Even using middle of the road quality, materials will run closer to $2000.
You figure labor @ $40 per hr (which is low)
Approx 3 weeks = 120 hrs (no body work)
4800 labor
2000 paint materials
-----
6800
minimum

Macco = scuff and shoot with JUNK materials.
But remember --- They don't charge xtra to paint everything ya don't want painted
