Since you're in Atlanta, check with Mike at Wings Camera. Mike is the genial master of Wings, which dates back more than a century, family owned since 1912! Here's the website:
http://www.wingscamera.com/ I don't know whether Mike does any repair work himself (he did free a really stuck filter on my Zuiko 28mm without damage to the lens) but he can certainly suggest capable people in the Atlanta area. $210 sounds high, unless it includes a complete CLA. If you check Ebay you may find an ever-ready case, if you find one consider replacing the neck strap. I've had good luck with dealing with repair shops by mail, I am now looking into a CLA on a Contax IIa.
While I am somewhat mechanically inclined - auto repairs, etc - I wouldn't tackle the Contessa's shutter. Mark Hama (markhama.com) in our area is a YashicaMat specialist; he worked in the Yashica factory building them. The 'Mat's use a leaf shutter like our Contessas do, I imagine that the Mat's shutter is more difficult to get at. I've never used him but I've heard good things about him.
