MMORPG Game like World of Warcraft

Im searching a developer or a team which are willing to work on a idea for a MMORPG like World of Warcraft, but with some unique functions. Graphic is required to be made aswell, but you dont have to do it, but you will have to find one which you work good together with. Graphic is not required being such as good as World of Warcraft, but just some graphic is needed. I prefer a developer which knows a good engine or even a open source project which we can work on from making this game, so that we dont have to start from the very beginning. By standart it should be pretty simple, and then we will later work on making more items, monsters, quests, NPCs, and functions. My unique function will I tell in a PM if I think im willing to work with you. The freelancer which get this job will also have to work on more things for this project in the future, which means more work and more money for you. I am also willing to give a good percent of the income of the game to the developers and graphicers which makes this comes true. Its also required that the developer can set up the game to work online trought a server, and can manage the server and keep it secure. Please let me know your ideas for prices for: - a small MMORPG World - with few monsters - few NPCs - few shops - auction house - armor - weapons - skills - quests - houses - cities - and so on for the defaults. Please also let me know what engine or open source project you will work from, and if you have a graphicer which can do the graphic. Thanks in advanced.
