Revising a Purchasing Flat Agreement

I am looking for a legal professional to revise a purchasing flat agreement. The scope of the revisions needed are major and there are specific clauses that require attention. As for the legal style or jurisdiction, I prefer a style of Tabilisi, Georgia law, but I require guidance on which style would be best suited for my agreement. The ideal freelancer for this job will have experience in real estate contract law and be able to provide legal guidance.
