Real Estate Litigator recommendation - Atlanta

I am in Atlanta and was sold a subdivided lot that turned out to be not properly subdivided and was never disclosed. I now have hundreds of thousands of dollars tied up in a property that the city will not issue me a CO or let me do anything with until subdivision issue resolved (after letting me pull permits for all renovations - separate issue).

I have spoken with several litigators and all seem to think a variance granted by city is going to be the way out of this, but that due to a few loopholes in Georgia law, I might not have any recourse with seller for damages.

I need a recommendation for a mean damn attorney that is ready to go sue the pants off this guy. Any help would be much appreciated
