Active Summer Camps

I am looking for someone who can write a WordPress plug-in for a Summer Camp site. The plug-in should be a booking system for schools, and it should basically work like this: 1. The teatcher will make a booking for the class. Receives confirmation mail, and payment instructions. 2. Teacher will receive login and password, and log in to make a list of participants (Name and contact e-mail). Mail to contact e-mail (parents) with login and password. [login to view URL] log in and fill in details about respective child. Confirmation e-mail and other information. It should also contain a front-end and back-end administration funktion. On the front-end administration, the parents and teacher should be able to managed only their own records, and in the back-end admin funktion, it should be possible to managed all records.
