Sue the bastard. It seems you have kept the records, that will be helpful. Get yourself a good lawyer. Best if the lawyer agrees to get paid only if and when you get paid. I heard lawyers will work for free, but will take 33% of whatever money that comes in. So, sue him for those 200 hours. Sue him for pain and suffering. Sue him for all legal costs - including lawyer and court costs. That bastard will think twice before he tries to stiff another person again.
