Invite script using social graph data

If you are a company please do not bid on this project. I prefer to give work to solo freelance developers. However, if bidding on this project you must write clean php/js and understand graph apis.... you must use APIs in accordance w/ platform guidelines and TOS. IF YOU HAVE ALREADY DONE A PROJECT LIKE THIS PLEASE SEND URL SO I CAN CHECK IT OUT. DOING THIS WILL INCREASE YOUR CHANCES OF GETTING THIS PROJECT. I am looking for someone to create and implement a quora-like invite script ([login to view URL]) that does the following: See [login to view URL] (notice USER AVATAR, PERSON'S NAME and INVITE button) The script should query to find, display and give users an opportunity to invite their contacts from FB, Twitter and Google Open using graph data. ***My current site already uses oauth from Twitter, FB and Google but currently does not import user contact info. *** When a user signs up using FB, the script should pull the new users friend list (phone+email) into db table When user signs up w/ twitter, it should pull following/followers (name + username) into db table When user signs up with Google, it should pull name/email into db table. We will discuss naming of tables before hand and all code should be commented out clearly. We can also discuss 'class' names in order to avoid confusion. How it works - [login to view URL] User signs up, authorizes the data we are going to use, we insert new users contact list which includes avatar, name, email. We then take contacts and display this info so they can invite or if the person. If the person is already a member we can show 'follow' buttton rather than 'invite' button. I have already programmed the 'follow' mechanism. If you have done a script like the above please share. Before bidding please go to Quora and see how they implement. Everything comes from graph.
