I am coming from a similar place but not yet launched my site. I have thought about the challenge you describe, and there are many on this site with advice that can help.

Whatever size voice you might have, it is louder when you use it locally. Are you and your friends using it to help people? Are the people then helped not willing to try it?

I can’t see your site from my current location but with local and modest goals you might be surprised who the influentials are and what karma they might really want.
