How do I get started in wedding photography?

I am a photography student at a community college and I want to start shooting weddings. I can't seem to find someone willing to give me a shot. I'm not great at photography, but I'm pretty good and the more I check out local wedding photographer's websites the more confident I become.
I would be willing to start off really cheap, but I need that first break.
Does anyone have ideas about breaking into the wedding photography business?
I am located in the Knoxville Tennessee area.
