Build a similair site, for listing events, connected with facebook page

I want you to find a script or copy or build a website like this website: [login to view URL] It's connected to a facebook page. [login to view URL] When you invite the page to a party it autmatically attends & automatically gets added to the website. On the website the list with event is build automatically & automatically update every 1 hour. Please build me website very similar to this one. Also i need a field to add events & a field to search event by postal code or city, just the same as on [login to view URL]
