I'm glad to see you posting about your own sitch so much these days! We don't get enough of you around here usually.
I am taking a childbirth education class with S., which is a 6-week affair. The business is booming, the classes are full, and the whole thing is run by a former midwife and educator who decided to teach her own classes after having worked for various hospitals and birthing centers. Why not start some kind of business like that? I'm not sure WHAT you would teach, but find a niche somewhere in your former practice and offer classes. I can tell you more about her model if you're interested.
I did a similar thing with a scholarly proofreading course I ran a few years ago. I decided there were a lot of proofreaders and copyeditors in New York, but none qualified as I was to do scholarly work for university presses. So I designed a course, marketed it to grad students in the humanities who had no hope for a job in academia (because of saturation, not lack of ability!), and ran it out of a rented space in Manhattan. It was a success, and I made a lot of money in a few hours. If I had kept it up, I could have rented my own space and started a school. But I went on to a different kind of editing, and so I let my course lapse.
Anyway, that was something I thought of that would take less time and net more money.
