This is a very bad Idea.
Invest your $$ elsewhere, or try a smaller project. There are way too many MMORPGs out there already, and they are incredibly risky to produce. Sure, there are a few success stories where the devs banked big time, but for every success story there are dozens of commercial failures that either got cancelled or closed shortly after launch due to lack of players.
Getting 15,000 players to play your game is a challenge by itself, and the technical know-how required to pull this off right is rare and expensive. I don’t think you’ll find that talent here.
