Is this possible?

Let's say I have a vbulletin forum. Is it possible to make it so the only person that can read all the replies to a thread is the person who created the thread?

Everyone else should see a message that reads "This reply has been marked confidential"

Oh, and when someone replies to the thread it gives them the option of marking their post Public or Confidential. Meaning, everyone can read it, or only the original creator of the thread can read it.

Is this possible? How? How much? Where? Etc...

Yes it should be possible. You'll need to hire a php programmer that can work within the vbulletin script. And how much depends on the programmers price and how fast they can get it done. All that is needed is an if statement I'd assume that matches the person with the creator's ID. If they match, they can read the replies.
