Social Networking/Chatting Website

We are currently looking for programmers who are familiar with MySQL, PHP, Java, REST( if possible) to help us out set up a website. The website will basically have a a user/Log-in page, then users with a specific ID should be able to enter different pages. Each page will be set up with a specific time. Ex/ Page 1 will go live at 10:00 EST. When it is 10.00EST then users with a specific account will be able to enter that page. The page will have a large shoutbox/chatting feature, enable users to play games, and upload .doc, jpg and video files. Members should also be able to privately chat with each other. The page will also have a rankings system based on uploads and game winnings. Each member should also have their own profile page that allows them to connect with other members. We want this website to operate smoothly without any delays. This is a fun project that should not take long to complete. It should look sleek and most importantly USER-Friendly( college students) we have an entire blueprint with specific directions in mind. See attached a short sketch of how we envision each page to look like. Regards, P and D
