Going into finance is one option. I went through a very extensive application procedure with a big financial planning firm (you've heard of them) and was offered a job. Ultimately I turned it down, because the hours wouldn't have been any better and I don't want to do door-to-door sales. If you think that might be a good fit, teachers are generally good candidates for that sort of job, and it pays really well. They were going to start me in the $70K range and promised 6 figures within 2 years. Top earners are in the $300-400K bracket.
You could also look into travel companies, fundraiser companies, anyone you've seen exhibiting at TMEA. They love to hire former band directors. I don't know that those hours are any better.
Ultimately I left my job as an assistant at a big HS (you've heard of it, perennial finalists at SMC) for a small private school (you've never heard of it). It was a pretty big pay cut. My budget is non-existant. However, at the private school I have practically zero discipline problems, the administration is awesome (aside from the budget), and because we don't march I get to home in the afternoons.
If the issue is time, look at private schools, middle schools, or schools that don't have the big competitive culture. You won't have a huge band that can blow down walls with a concert F. Nobody will hear your name announced at SMC, you won't win honor band. You WILL still make a difference in kids lives before you go home at 3:30.
