@Square: At the moment, we're looking for a tileset (or a few tilesets, hopefully) that works with the concept of the game. Because the mapping style will depend entirely on this tileset(s,) I can't hire any mappers as part of the project team until I've found a tileset that will work. I'll keep you in mind, though.
@SP: Sure, I'll put you in here. I'll let you know if there's something specific with which I could use your help.
