Can't Find Plugin

So I am looking for a plugin or theme to achieve the following Idea:

I would like to have a place where individuals register and request that their loved one’s name be added to a list for an event. There is a set of 5 criteria and you have to meet one to be put on the list. I would like for these people to each have a private location where they can receive status updates about their honoree, and if the request is valid then they will have a confirmation page with arrival time documents and the like.

I can’t seem to find something that will accomplish this. Any ideas?
