Hey Shiloh,
I live about five miles from Jays Brewing in Manassas. Yes, he definitely caters to brewers, but does have plenty of bottles, carboys, etc. Basic things like K-meta and iodophor can be had there too. He just started carrying some basic kits as well. There's another place in 7 corners, though I've never been there. It's called My Local Home Brew Shop. They are at mylhbs.com
