I just read the answer you got and had to laugh. I'm a Painting Contractor in California. I laughed because no one has said what is involved in your job. Did the guy who answered have the inside or outside painted? What was the prep involved? What type of paint was used, flat, semi-gloss? Was primer needed? If it was inside, was the ceiling painted, trim painted or just walls? Did that price include the paint? There are so many variables associated with the cost of painting...to quote 45 cents is rediculous. Was this a licensed contractor? I doubt it for that price! The best advice I could give you is get a minimum of 3 bids and talk to family and friends to find somneone who has done work for them. If it's more than you have to spend, either save longerget more bids, (they are free), or do it yourself!
