ZipZapGuy: What more information do you need?
Not a particularly inviting answer. Take a look at almost every tournament run. It will advertise the specifics of the tournament when soliciting entries. Does responding to this thread sign you up? Stuff like that. Slor would be an experienced organizer that might be worth talking with.
It sounds to me like you want to take the NCAA bracket and use the 32 team part of it with a 1 and done theme. That's the easy part. Organizing it requires quite a bit of attention to detail. Are you up for that?
