There's a thread on BGG I wanted to make sure everyone saw. Rio Grande Games is sponsoring a game design contest in which each finalist will have the opportunity to sit down with Jay Tummelson face to face and pitch their game. Last year he agreed to publish 4 of the entries!
Even if your entry doesn't win, the opportunity to get direct feedback from a publisher is pretty good, especially considering there appears to be no or very little cost to enter.
Watch the BGG thread for details on entering the contest, and good luck!
I'm afraid I don't know the answer to that one.
