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 .
You might pay an additional $1 to $5 per square foot for optional repairs and updates. Consider having your molding, trim and baseboards checked while you have a professional in your home. This might be a good time to upgrade or repair any cracks, warps or other issues. Pros can usually touch up or replace these items for an affordable rate, and they may even package such fixups with your project.
I have the time since I work from home and work has been slow, so I volunteered to paint our kitchen..10 X 16. My hubby changed his mind midway through the painting, so I had to change color. Took 3 days. I did most of the painting and he painted and did some touch up work. We spent $126 in paint and supplies which included primer, ceiling paint, primer, three colors, semi gloss for trim and chair rail, assorted brushes, roller covers, and drop cloths. After all was said and done, it looks really good.

"Rafael was very professional, detail-oriented, pleasant to communicate with (responds promptly, returns calls, confirms appointments) and always showed up on time. He painted my daughter's room beautifully and for a reasonable price (offered pricing with and without paint). His work was precise and without mess. I will definitely hire him again for more painting projects."
