I'm a fairly light RP'er, but I've been trying to do a bit more here and there randomly and I actually joined Tylwyth Narah to get involved in more questionable activities and what I have been involved in has been fun. That said, I don't believe TN really has a front, though the organization does deal with some illegal trade but under no facade, just all in secret. (C'kayah can correct me if this is inaccurate.)
I really like the idea of a front for a criminal organization, though at least personally, I'm not sure my character would get involved if you're planning a trading organization (she's not much of a merchant or crafter). Personally for my character's venue, I sort of picture a bar, restaurant, club-like place, where you have a back room where deals goes down, or a warehouse of illegal goods in the basement, or hidden reinforced rooms for kidnappings, etc.
(Image of Chinese restaurant with a back room where people are illegally gambling playing mahjong suddenly flashed into my head.)
