Minecraft Mini Game Idea

I am looking for builders and redstone geniuses to help me create a mini game. I have not decided on a name yet but i will take any suggestions. The game will start you off in an arena with about 15-20 people where you have to be the last one alive. But there is a catch at random points in time you will be randomly teleported to a different arena with different players. You can be in the same arena or you wont. If you would like to help out please email me at rvngedadawgs@gmail.com. I also would like someone to provide a server for the arenas to be worked on. The server would need to be bukkit for the plugin world edit. Also i am looking for people with great artistic skills to create a banner for the game.
