But the question is what you can reasonably salvage there. I can't imagine a reputable general contractor would venture into such a minefield and take over the mistakes of their predecessors. Regardless of the price. The market is simply too good right now. If you want to finish building the house, you will probably have to contract the trades individually. For that, you need a reputable architect/engineer who coordinates everything and can get craftsmen through connections. You will probably need a considerable amount of money to first undo all the mistakes. I wouldn't count on GU2 anymore. It's nice and all that he still has real estate, but you yourself don't know if they aren't already encumbered elsewhere. Someone who causes that much shoddy work certainly doesn't only do it on your house.
