Rockhurst University Fall Tourney

With Rockhurst University being in a nice central location. I was thinking about hosting a fall tournament. The tournament would be open to all teams and we would use Rockhurst's nice field turf field. I would shoot for Mid September to Mid October. Fee would be the cost of refs and depending on how many teams show up and I will make the schedule so that everybody has equal games.
Just to get an idea of who would want to show and tell the school how many teams would possibly show. Who would show?
