Pretty much what twtmc said.
Also, instead of choreographing the dances yourself, why don't you guys just pick a well known already choreographed dance (Hare Hare Yukai [so over played but still an example], Happy Synthesizer, Only My Railgun, Bad Apple, Spring Shower, PONPONPON, etc)? It'll be a lot more interesting to the audience that way... Especially because some of them probably already have seen, or know the dances.
