Anyone local to me capable of correcting errors on a 904 race build

I've been in a similar situation with a machine shop years ago that I hired to build a 360 when I was hurt and could not do it myself. There were so many things done wrong there was no way in HELL I was taking it back. I called an old high school friend and he helped me fix everything that was wrong.
I had a situation like that too many years ago. Had a local machinist fly cut valve reliefs and we miscommunicated and ruined the pistons. Ended up in court. I was out the cost of the pistons plus the machine work. He felt he should get paid for the work he did even though it ruined the pistons.
Went to court and the judge forced us to settle on our own. I gave him the pistons outright for a full refund of the machining.
Compromise. These things happen and it not pleasant.
