BuddyPress.org

Hi, I have different types of users on my site and I was wondering if there is a plugin that I can install that if a normal person just click the Register button they get taken to a standard /register page, but if someone wants to register as a speaker or vendor they can click on a Register Link on specific pages that will go to /register/vendor or something and it will ask for more information.
I would like for the normal users to just get a standard activation email but the other user types to have to be approved.
Is there anything out there even close to this? Or at least the first part and I can figure out a way to hack it apart to do the manual approval?

Thanks!
