After losing power for 20 hours recently, I decided to get a generator to power the whole house. Bought a portable one and installed a 50 amp inlet going into my breaker box myself, with interlock to prevent backfeed. $1500 total.

Same here, I did hire a roofer, painter (exterior), and driveway contractors because both of those are a pain to do alone if you have a full time job. I am doing all siding/trim repair, building my porch, new doors, windows, all interior work etc. myself. I had some experience and plenty of mechanical ability before this past year, but just dove right in recently and realized most work is not that hard, just a takes time to do alone.

If you find a cheap contractor in NH, you will also find a shitty contractor in NH. I am remodeling my whole house, and after having several contractors out giving some quotes and doing some work, I decided to do everything myself.
