I recommend The Plumbers Inc. in Kennesaw (http://www.theplumbersinc.com/). Their phone number is ###-###-####. Sometimes you can find $45 off coupons in the mailer magazines you get in the mail. I know that's not alot but it helps.
Our sewer pipes went uphill, so we had to have part of our garage dug up and a good chunk of our side yard dug up, too. Bob is the one who came out to do it. He made a special effort to explain what was going on and stopped by on the weekend (one of his days off) to explain what needed to be done to my husband rather than explaining it over the phone. (You know how husbands sometimes don't believe what their wives are telling them!) He came one other time to unclog something else. I used to work in real estate and these guys came highly recommended to me. Good luck!
