I helped to launch a co-working space in a community of 12,000 in the Sierra Foothills. (Although I can't claim any credit at all for its current implementation. :-) You can check it out at
http://sierracommons.org/Contact Robert Trent there at (530) 265-8443, tell him Rob thought he might be willing to talk to you. If you can get him to slow down for a few minutes, he'd probably be very willing to tell you all about what he's done.
In short, they've managed to take a run-down space above a restaurant, and turn it into a beautiful co-working space. I think they managed to fill every available desk within the first couple of months, despite being (IMO) way pricey. They've done a lot of it through grants, so definitely ask him about that.
If you'd like to know anything else about the project and can't get ahold of him, feel free to drop me an email -- address is in my profile.
EDIT: Just to be clear, all I did was start a "solopreneur" group in the area, and shortly afterward, start pitching the idea of a co-working space. Eventually, I met Robert Trent, who had some extra office space and graciously opened it up to anyone who wanted to give it a shot. He and I debated different models for a co-working space. I disagreed with some of what he wanted to do, and eventually lost interest. He took the project the rest of the way and ran with it, and has done a truly amazing job of pulling it all together. It's still not what I had originally imagined, but he's the one that actually made it happen, and it's certainly successful. So, all props to him.
