This is required in Wyoming?We are lucky in the fact that we can do a lot of the work ourselves. DH knows plumbing, electrical, rough framing. drywall, tiling, etc. We could probably build a house by ourselves, except for the county requiring certified professionals to do everything in order to pass inspections. I trust his work over some of the "Pros" out there nowadays. He has fixed so much on our current house that the pros did half-assed. Only one valve in the entire water system - and that was right after the pressure tank. In order to pull the toilet to paint the bathroom, we had to turn off the water to the entire house.
