B. I wonder if you can get some kind of gig work income that doesn't involve background checks.
C. I wonder if you might be able to develop some other source of income that doesn't involve background checks. (For example, I looked into panning for gold at one point.)

Yes I'm looking into perhaps putting together a classroom on one of those pretty killer live educational apps that are available these days. I used to teach guitar 30 years ago and I really enjoyed it, although I'm not sure I'm the best teacher ever.

Let me know if you want links to some of those resources.
Best of luck.
