Charity Event planned for June Homestead event!

I am planning a charity event for a local charity I chair with Ferraris in Homestead.

Plan is to participate with the Challenge car at the Performence Drivers Club meeting in Homestead Speedway in early June and offer a 8 lap ride as a passenger to five participants. The event willbe fully catered like a race team, a hostess on hand to cater to the needs of the participants only (spelled LIZA will be hired), pictures taken by a photographer, etc.

I hope to auction off those packages on e-Bay.

What do you guys think I should start with? $ 200/person?
