As an owners rep and former estimator for a gc i do expect to pay a reasonable deposit say 10 percent and then weekly progress payments. I am asking the painter to book his time and to do the work on my schedule. Most painting companies are not huge operations they will pay their staff weekly. For most repaints i ask for one tinted primer coat and one finish coat for 100 percent coverage. New work gets one tinted primer and two finish coats for 100 percent coverage. The cost of the paint is not really that different for colors or finish. Brands like european fine paint and C2 are more expensive than Ben Moore and sometimes more difficult to roll based on their consistency. Some home depot brands are as expensive as the Ben Moore and of equal quality others aren't. Red paints are notorious for number of coats required and special priming requirements.
Consider purchasing supplies personally to save money. Ask the painter for a bid that separates labor and materials. Then explain that you'll purchase the materials and ask for a list of exactly what will be needed to complete the job. Caulking, for example, is an extra supply commonly used to fill any cracks or damaged areas in your walls -- and one that might be overlooked in an incomplete list.
I hired Harvey's to paint most of the interior of my house. Harvey was so nice, professional, and answered all of my questions. The paint crew was also fantastic. They did a great job and managed to finish the job quicker than originally planned. I plan to use them again in the future to paint the rest of my house's interior because they did such a great job.
