I am not sure how it would work out for a family law practice, but I know a few people who pick up clients by giving presentations or teaching workshops to would-be business or real estate owners.

You had a successful practice once, you can do it again. You did have some good reasons for quitting that job. Yeah, maybe there were some reasons not to quit, but you will be okay once you get over this hump (this is the point where my boyfriend would elbow me and say 'get it, get it? Hump, like a camel?')

I would contact all the small business advice organizations in your town. SCORE, SBDC, county extension -- not only will you get advice from people who help small business owners, but you will be in contact with lots of people who may be able to refer business your way.
