MMOCC, Virtual World Desing and Programming

Hello Need to develop a similar MMOCC [login to view URL], but with many differences. At first need to: 1) Avatar Creation (Design character with change of hair, clothes, pants, shoes, and colors) 2) Chatting (Chat is entered, appears in the game inside a chat bubble, and eventually disappears) 3) Credit System (Users purchase credits through PayPal, SMS and Telephone, which are automatically delivered in-game and can be used to purchase virtual items, clothes, etc) 4) Catalogue System (Add items, Lists all items, a user can purchase an item with credits, and their credits get adjusted. The item is put in their inventory) 5) Items (Create for the users, Can be moved, placed, and rotated inside rooms, or placed into the users inventory) 6) Walking/Talking (Users click to move to a position, can walk around objects, behind objects, interact with objects) 7) Trading (Users can exchange items for other items, or for credits- with another user) 8) Admin System (Can manage other users information, credits, Ban Users, Mute Users, etc) 9) Room Creation (Users can create a virtual room, name it, lock it, unlock it, place items inside it, and decorate it with virtual items) 10) Friend List (Users can add friends to a friends list, and private message them in-game) 11) User Items (Users can create their own objects and sell) 12) Stores Users (Users can create their own shops and businesses which offer services or items in exchange for credits) The server will have to be capable of handling a large number of users at one time After the game is produced, you may be required to continue to work on the server and client, doing changes, fixes, and upgrades, which you will receive additional Pay for when that time comes.
