Painters with bad reputations can avoid the problem of reference checks by giving their customers lists of relatives and friends.  The people will say great things, and the customer won’t be the wiser.  The best way to avoid this smoke and mirror trick is to ask specific questions about the project. If the reference seems hesitant, doesn’t know the details, or gives sketchy responses, be skeptical. 
Brown denotes a personality that is earthy, realistic and trustworthy. This classic earth tone can be applied to living and work areas alike, as it evokes a feeling of being well-rounded and connected with nature. Terracotta and dark mustard brown combinations are perfect for Latin American and Santa Fe-style décor. Brown hues are great for interior spaces that get a lot of sunlight. Lighter shades of brown, such as beige and taupe, are neutral colors that particularly work well in homes that are being shown to potential buyers.
Being in the business for 25+ years I have had the privilege of working with thousands of clients. Although they all came from different circumstances and backgrounds they all had one common goal in mind. Every one of them wanted to be respected, receive top value for their money, and get the best possible paint job for their most prized possession, their house!
When the homeowner is at the point of hiring a painter, they generally will have colors selected or at the very least a color in mind. I always ask for the colors before I bid a job. Dark colors, high sheen colors and specialty finishes require more labor, this drives price. If its not a color change or I'm going over a similar color I give the pricing option of one or two coats. The best advise I can give based on 25 years in the business is to put it all in writing,colors, brands of paint preferred, when the work can be done, who moves furniture and how payment will be handled. I never get up front money. BTW you most definitely get what you pay for with paint. Higher quality products results in and better looking job. Don't be a cheapskate when it comes to paint or the painting contractor.
Calculate your costs.Having an idea of the cost of paint you need to purchase will help obtain quotes from a contractor. “Paint coverage is based on how many square feet of surface one gallon will cover,” says Bunting. “Most paints will cover approximately 400 square feet. Tally this by multiplying in feet the wall’s height by its width, minus windows and doors.” Determine how much paint is needed to complete the project. “To calculate the cost of a project, factor in the day rates, the size of the property, any architectural features, and the paint finish needed,” says Rance.
