If all else fails, shoot into the crowd

Calling out the brain trust and cashing in my connections here:

Let's say for the sake of argument that I have a draft of a contemporary fantasy novel that I wrote (spoiler: I do). Let's further hypothesize that it's really, really good, as in good enough for publication by an actual publishing house rather than, say, Lulu (spoiler: it is, and I've been told so by a bunch of people). So at this point, I need to talk to That Person, the one who'll put some forward motion toward that goal. Who is That Person in this case? Who should I be getting in touch with?
