Your best bet may be to simply donate a game to the BGG.con library, then talk it up here on BGG, and hope to encourage poeple to check it out.
Or, you could always donate a game for the raffle. BGG.con gives away a lot of games. If you donated one it could be given away in front of most of the 1000 attendees.
Thank you! I believe this answers my question.
