Not sure if you've already found someone. We've had very beautiful shoots by both Bonnie colbourne, more edgy style, in leesburg va and jgoodale photography, more of a journalistic style and cheaper, in mt Vernon va. My girlfriend got a package from little moon photography which was really sweet.
I don't know if you found some one yet, but you can contact Alfred at alfkammsn.com, he's in NOVA, he'll come to you. He's really good and reasonable. Hope this was helpful
