Auditorium seats facebook promo application

We need a small application where there will be 5 tabs: first with just plain test, information about the app second with the prizes third with option to invite friends (the invitations needs to be tracked) fourth with contact information fifth with actual game. There will be auditorium with 500 seats. The user can zoom and move in the auditorium (arrows on the site - JS), she will select the seat to sit on and confirm the selection (window with row and column number of the seat and two buttons - confirm & cancel). After the confirmation the profile picture will be placed on that spot. She can see all other people where they sit. Some of the seats will be winning, who invited the winner will receive small present, so we need to track the invitations. It need to be written in PHP with MySQL. The deadline is 8 October. Please provide example of your work.
