In almost any music store there's a bulletin board where people looking for gigs, or seeking band members, post notices:

Check those out. You might find a note from someone looking for the same thing you are.

Or, post your own. Lots of people who frequent the guitar shops are right where you are, looking for people to play and improve with. A note from you at your local Guitar Center might introduce you to those folks. And who knows where that might lead?
