R.S.
just doing a quick search I found quite a few links for you:
http://www.vahomeschoolers.org/support/
http://www.homeeddirectory.com/states/Virginia.htm

http://groups.yahoo.com/group/NoVa_Waldorf/
http://groups.yahoo.com/group/RiverbendGarden/
I am in Ashburn and I know quite a few people in Leesburg who homeschool- I'll try to find out what I can from them so that I can give you better information.
hope this helps!
