I'm confident that you can do a great many things and that you know your abilities better than anyone who will respond here.
As far as I can tell, your only complaint (other than the low quality of the work, which doesn't seem to be of much concern to you) is that the guy hasn't given you a receipt. That doesn't give rise to any sort of legal issue. Hopefully you paid the guy with a check (don't ever pay a contractor with cash unless you get a signed receipt at the time you hand over the cash). If you did, then you can get a copy of the negotiated check from your bank, and that can serve as a receipt.
