Game Developer for Big social network

Okay guys... here it is a long shot haha! I am a developer of a soon to be big social network... I am the main developer... there for I know some pretty mad skills in the PHP, JavaScript, MySQL, html, css and jQuery side but as you all know the google + will be coming out soon and with facebook being our biggest rival atm I need something which will make it not like anything else.... This is going to be a very big project and need someone which will be 100% committed as I need a very big game and that is a very big ask especially how I am asking it to be for FREE... haha yes you heard right (free)... Now here is the upside... from my years of development in webdesign and graphics I have grown to quite a large figure in the world of development... I can do all of the scripting in PHP etc as as you have guessed I am a very advanced coder in the website side.. I hand code everything and hand design everything using notepad++. I do not believe in any platforms so i require a game designer/developer which can make the following from scratch..... the game will be on the website multiplayer character customisation role play (quests etc) a bit like the game world of warcraft... or runescape but with a much different story line... I believe if I can get game/games on my website which not only has this amount of power and FUN... but also connects to the social side of the website sharing with your friends what quests you have completed etc... THIS WOULD BE GREAT.... and infact you as an employee can help think of more ideas on the website(not asking for u to develop them) ... all the website development will be by me... now back to the FREE thing... it is not technically free. As you are going to become apart of the websites team therefore getting a percentage in the company which we can talk about later... meaning any money I earn from the site you will also earn some money... last bit of my attempt to persuade you.... I work all the time on this social network and have alot of friends and family willing to make the switch from facebook... if we have someone like you who can do this game think how big it is... now people I just say that one thing... imagine a website like RuneScape a game with millions on players then imagine a social network like Facebook with billions of members... now but them in a big mixing bowl and mix them up... what do you have??? you guessed it something that has not been done yet and it could be a very big success.... I understand the server power needs to be alot and I will sort that out hopfuly. so come on get in contact ... help me change the way people use the web.... :) thanks and it only says 60days as that is the max i can have you can have alot more as i understand this is a big project... thanks leave your skype msn yahoo anything and I will contact you
