I didn't think any non-theists lived in my town until I started an atheist meetup (meetup.com). We'd hang out and have beers, basically. I met a lot of very cool individuals that remain my friends today. I can't believe I was missing out on them! Ever thought of doing something like that? You wouldn't even have to say it was with the intention of finding a SO. You could just see what happens, and if you don't meet an atheist chick, you made some friends maybe.
