[REV SHARE] Looking for RPG level/maps/contents designer

Hi, I am the author of Hartacon Tactics, the game is a strategy-RPG with 2D isometric maps. You can find more info here:

The game is technically almost complete and now I am looking for a passionate contents designer, to fill the game's world with maps, weapons, armors, skills and so on, and balance everything. This is not strictly an artistic role, although map creation requires an artistic sensibility to a certain degree.
I plan to release the game for XBOX 360 soon, and the position is paid on a revenue-sharing basis.
