A good friend of mine teaches at a store called Drum N' Strum. I don't know where you live, but the store is way way out in Warrenton, I think. He lives in annandale, and also gives lessons out of his house, so PM me if you're interested and I can help you contact him.
He's a great guy and a great great guitar player. He can teach just about anything you want I'd think.
As a side note, he also used to own the chain of Record Convergance stores that were around Fairfax/Falls church in the 80's and 90's, if anyone remembers them.
