Wrong place - this is the section for posting stories, not for asking for sign ups.
I'll move this to the writer's lounge subsection, but I'll also mention that if you want to write a fic this isn't the best way to go about it. (And if you want people to write the parts themselves/their own characters, check out the RPG (Role Playing Game) section). You won't get as good a feel of the character if someone gives it to you as one you create yourself, generally. As for the style... again, that really should be up to you. What style of writing do you want to write?
