What attraction can i include for a Fundraising Dinner Dance on Valentines Day?

I belong to a marketing institute and we are looking for fund raising ventures that will make the institute self sustaining. Our 1st project proposal is to offer coaching services to marketing students, so to raise funds for this project, we have decided to host a "Valentines Day Fund raising Dinner Dance. What should be our selling point for this event so that people can turn up in numbers and pledge their support?
