What is an average price for an 18'x25'x8'H room with 1 window and 1 door. No prep or materials- Labor costs only. Also, how much for the ceiling (flat, no molding)separate?

Hi, I would charge about $450... ( $100 for ceiling)... 2 coats on everything... ( tint your ceiling white a little if they want a white ceiling) .Should take 1 1/2 days...
