Jyothi, you are quite lucky that there are a number of respectable painters who are members here at Hometalk. Here is a listing of those closest to your area: http://www.hometalk.com/?industry%5B%5D=48&zip=30135&search=contractor
thank you so much for the info
Check out Hometalker Peace Painting out of Alpharetta. Not sure of their service area - but we've really enjoyed all their Hometalk posts & beautiful work they've showed off! =) http://www.peacepaintingco.com/
Happy to help. Please let us know how things go and if you need any more help with anything.
Jyothi, Douglasville is outside our beaten path but you can call your local paint store, tell them what you need and they will pick out a contractor to recommend.
