I feel your pain. its very rare that I will erect iron that my shop didn't fab. If it is then its strait time across the board at full field labor rates I always have to remind them that I have WAY cooler ways to loose money than busting my ass for them.
I take it no 3rd party inspector to take the heat for mile wide fitups?
More money more problems, seven figure years bring six figure tax bills. I would much rather have five 10K jobs in a week than one 50K job. Your going through a period of being jaded, some times you gotta step back and figure out I your need to find something else to venture into. For me it was the fact that this is all I know how to do. I could do something else im sure, but this is all I really formally know what to do.
