As a man who dated a lot over 20 years I feel you should give your sons this advice. That bullshit they're putting up with is their own fault.

I hate Chambers of Commerce but it may be worth it to join one for a year to help develop some leads and to source an accountant which other small biz owners count on. Also, Quickbooks is fairly easy to learn yourself if you're so inclined.
I had a similar, though less rapid exit once. Boss was a known bi-polar executive who used to routinely cuss people out. I always said that if he ever tries that with me I'm out. Of course, eventually he did. In fact, his behavior issues were affecting managers all over the building and blowups and sometimes fights were becoming routine. The most hilarious part is that it took me one week to find another job and the day I went in to quit he offered me a promotion. I still resigned.
