I only did  a quick look at dc providers, im admitably not familiar with that market but tia phoenix is a reputible provider and posts here on this board often, but she tours, not based out of dc.. try sending her a pm

You may want to try to contact Jawanna or Allison. They may or may not be into this sort of activity, but they have both been in the area for awhile, have great reputations and maybe able to point you in the right direction.
