Top poker player for charity event

[Apoc]

Hey gang,

Not sure where to start on this, but I'm a student in Chicago who's in charge of putting together our annual Casino Party in May, for which all proceeds go to charity. This year, the charity is Fabretto Children's Foundation (www.fabretto.org). Texas Hold'Em is always one of our big draws, and in my optimistic world, I thought it would be fantastic if I could get one of the top poker players to make an appearance, and (in a really ideal world) to perhaps donate a few hours of poker lessons, to offer to deal for us, or to play for an amount of time in which we charge players more for the privilege of playing at the same table. Any ideas on who I should contact and how I would go about getting a hold of them? Feel free to send me a PM or post...

Thanks!
