M. -
Have you considered doing freelance in your field? I used to work with a woman who was an HR whiz - but found herself too old and priced out of the market (how very sad...). I met her while she was filling in for our receptionist who was out for an extended period. Anyway, she started by just calling on friends at other companies and offering to sort their resumes for open positions and do the first round of phone interviews, etc. She also makes money helping people polish up their resumes. This would take some initial work on your part, and might take a while to see a return, but if it's your specialty, I'm sure it won't take long to get up and running. You could set up a simple website to direct people to. It's worth a shot trying in the interim.
I do wish you great luck in your search...
