I was surprised to find quite a few possibles on Craigslist for my area -
under the [etc] and [part time]

seems like many are from small business needing just a bit of help- would be a way to test the waters to see what might fit or get more ideas from.

I think the security consultant thing would be awesome for you- your core target group could be small businesses, single women & moms.
They might be more comfortable dealing with a woman esp a former police chief.
I bet a perfect niche for you!
