I recently went through the same thing. I ended up sending it to a place I found via a Google search. If you send it to an visa agency, it doesn't matter what state they're in.

The best deal I found was $110 Brazilian fee, $39 agency fee, plus $6 s/h.

I got my passport back in less than 2 weeks after I mailed it. Just remember you have to use it for the first time with 90 days of issuance.
