"I had Sam and his team come in to repaint our kitchen cabinets that were originally a dark wood stain. He cleaned, sanded, primed, and put on 2 coats of sheer white on both the doors and frames of the cabinet and they came out great. The kitchen is much brighter and even up close it is hard to tell that the original cabinets were not white. They were prompt and very communicative over the phone. We may soon hire them back to paint the kitchen next."
Whether doing it yourself or hiring someone, buy the best quality paint you can afford; it lasts longer and in some situations requires only one coat of paint instead of two. Painting a room usually involves prep work, primer and latex or alkyd paints with a range of finishes. HGTV.com gives a quick overview  as well as a list of painting dos and don'ts .
this was the estimate i received and well - hard to describe area - double hight ceiling entry foyer plus stairway up to hallway. painted hallway as well with 2 coats plus did a coat of white over all trim/molding/door frames - 6 of them - and repaired some minor molding cracks. we are supplying the paint. at first i thought this was high but then, well, it was better than doing it myself and the painter was highly recommended and he's very nice.
"C&A was not the cheapest company, but it was the only one that offered full service (removal of waste and carpet installation), and showed some real interest. Furthermore, the sales representative was on-time, polite, and always available. The finished job looks great, the crew was on top of its work, and they left after cleaning thoroughly, which not that many companies care to do. I highly recommend them."
