Since MMORPGs are subscription based anyway you would probably be interested in Nuclear Glory. They have an option where you set up an account, the first couple of users are free, then once you get more people they pay a subscription covering your server costs, you just sell the game, and all or part of the subscription money pays off Nuclear Glory.
If you are really interested in eventually working up to an MMORPG, first start in small increments. Work your way up to a small RPG (when I say small, I mean you can walk around a place and get into battles and talk to people, nothing fancy). Then make a small multiplayer game, starting with a chat client, then moving up to PONG online or whatever. While you're working on this you can post here and we'll help you out with what you need. New forum attitude should be: MMORPGs are not impossible, they just take a long time.
Good luck, keep posting.
