Drywall contractors price jobs on a square-foot basis with a premium attached to a small job because it is difficult to schedule and not as profitable, due to all the travel time. So this may be a job to do yourself. If the job is large you can find a contractor to repair a sagging ceiling in the Yellow Pages and classified directory under "Drywall Contractors" or get a referral from a friend or neighbor. Online you'll find these professionals in search engines like Bing, Google and Yahoo and at a contractor referral service.
