How did/would you find your doula?

[TeniBear]

As the title says, how did you, or how would you, find your doula?

I'm finished almost all of what I can do from my doula course books, so I'm really going to get stuck into trying to find some births to attend. I've got thousands of business cards (literally - I keep ordering them from Vistaprint because they're so cheap ), a website, a facebook page, I even just got a tshirt today with my website address! But I've only had one person contact me, and they never got back to me after a short email exchange. (ETA - Damn, I'm a big fat liar, I've had two contacts. I chickened out of the first one because I wasn't confident enough then.)

So, what else can I do to get out there? Where can I hand out my cards without feeling like a complete doofus? How do I get the conversation rolling?
