I really didn't have good luck last year with financial transactions with people who I would expect to use better judgement. Makes me lose faith in humanity to some degree, but I digress. I literally had someone stiff me $3k, and dipped on a job I hired him for. Blows my mind. Not to mention it was my neighbor's brother. So I can definitely empathize with you.
If he hasn't come through for you by now, it's probably never going to happen my dude. Good for you for keeping after it though.
