Men required at the Aust Open Tennis

Hi there, i am trying to find a group of guys to work at the australian open in a performing/character capacity for a major sponsor. Does anyone out there know where i should start to look. The tennis runs from 15th - 18th Jan 2007 so i don't have a great deal of time to get it together. I need 40 performers to carry out acts of good deeds whilst dressed as a genie. Has anyone got any ideas?
