School conference registration plugin needed

Hi,

I’m looking for a plugin that parents can use to signup for teacher conferences. I need to be able to add time slots for each day by teacher. I would also like for a parent to be able to compare availability for two or more teachers, so they can consolidate their conferences.

Can anyone recommend a plugin that will at lease make it possible for me to enter teachers and their slots and for parents to sign-up for a particular slot.

Thanks!
