Quite a bit of MSCs located in Atlanta, as well as companies outside of Atlanta that offer work within the city. One company that comes to mind that is in the Buckhead section of Atlanta is AboutFace. I've visited their corporate office, and it is a work of art. Plus, the owner and CFO are actually very cool and usually contribute to both MSPA and IMSC functions.
Good luck in shopping Atlanta, and bring plenty of quarters for the Georgia 400!
