It's not possible to hire Americans to do this kind of work without getting screwed. If you don't want to get screwed, you have to start doing this work yourself. (Or maybe someone in your family could do it? Do you have a 19yo nephew?) Not everyone is capable of some of the manual or cognitive tasks involved, but not everyone you could hire would be, and most of the work is of the simple-yet-laborious variety.
In the 3-county rural area where I've spent most of my time recently, we have 3 Lowes, 2 Home Depots, a Menard's, multiple Orschelns and Tractor Supplies, and probably fifty smaller hardware stores and lumber yards. This is many thousands of commercial square feet basically devoted to home improvement, for an area with fewer than 140,000 residents. If it were possible to hire this sort of work without significant expense, the home supply market would be very different.
I'm not criticizing any carpenters or plumbers here. Their work is naturally seasonal and cyclical, and our society DGAF about people with that sort of work. If an electrician would wire your new bedroom for less than $3,000, he wouldn't be able to afford $1,000/month for medical insurance for his family, at least not every month of the year.
