Board Game Art for Cards/Board

I am creating a science fiction boardgame and need to illustrate the playing card deck and various game components. It's a large project. Most of the art should be line drawings/sketches, possibly a duotone, to fit my theme. The game is a political game where candidates (run by a player) are attempting to be elected prime minister of a space colony. I really like this sketching style (and coloring) for the game: [login to view URL] Can you show me some things similar, or perhaps give me an idea of your vision for the game? Also, I need to get an idea of time frame to get this much done. Obviously, it's a lot so I might need to split it between artists. The file shows everything I need to get illustrated. I am looking for a piece rate rather than an hourly rate. This is a personal project that, if it goes extremely well, I might break even on, so I just can't spend an infinite amount. My proposed fixed rate is for each piece of art. Thanks Jason
