Crack The Vault Game

What i want is a basic Crack The Vault game. The user will see the front page with a place to put his guess and click on submit. If he is right, he will be directed to a page where it will tell him he was right AND send him an e-mail telling him he won and instructions on how to get the money prize. There will also be a weekly hint released and shown on the front page. The user will also be able to purchase a hint by paying with paypal ( hints are stored at the database and can be edited / added / deleted by admin). I also want to display the jackpot on the front page and everytime a user purchases a hint, the jackpot rizes by 10% of the ammount he paid for the hint. This will require also a basic admin panel to manage the hints in the database, manage the cost of a hint, manage the sercret answer and manage news to show on the front page.
