There are lots of places you can go, to start with go back through "this week in startups" they often mention various places around the US and occasionally around the world.
Many cities are now starting up with incubators, accelerators and the like. After the discussion between @ZulyGonzalez and myself in this answer about accelerators I would suggest you try for a new one just starting up, there have been over 80 spring up after Ycombinator kicked off and showed everyone the business model.
New accelerators will have less competition, be able to give more focus to you and be able to kick start you far more effectively, plus there is likely to be one closer to your area where your personal support base of friends and family are.
