Browser Based Online Game

Greetings Everyone. I used to, with the help of a coder friend, run a few browser based text games. It is a wish of mine to start a new one. It will start out as a browser based online game, and with all luck, with player interest and financial support, move to a more MMO graphic and perhaps even 3d Game. Game specifications 1) Player Avatar (Small changes in appearance) 2) Equipment (Armour pieces, weapons and cosmetic apparel) 3) Ingame messaging system 4) Real Money Bonuses ("VIP" Rewards and items) 5) Quests and quest related items, basic structure for fetch and kill quests. 6) Full market system for trading items 7) Classes (Miner, Hunter, Smith Etc. Unique stats and ability to do different tasks depending on class) 8) Class Specific duties (Equipment creation, recource gathering) 9) PvP and NPC battle systems 10) Levelling, experience and advancing skills. 11) Towns (Possibly. Items and equipment recieved based on players location) 12) Admin system for banning, editing and rewarding users. Just a shell to start with, but as more users start to join, and money comes, I will be more than happy to pay for more things to be added, as I have many more things I wish to integrate, but wish to keep the cost low to start with. All questions welcomed.
