Viral: Pizza making

I want a viral made. Based on an old game Pizza Tycoon. The idea is that a person logs in, on a special page on the website (leaving his name and e-mail) and then gets a short introduction. After which he makes the pizza, after completing the pizza a jury gives him a grade. After which he can enter 5 e-mailadresses to which he sends the viral. A gradelist is shown with the topscores. The winner gets a price after two weeks. The website is a Joomla website, it needs to be compatible. The e-mailadresses need to be inserted into the newslettermanagement (if possible).
