Q&A to Specialist and Notification

Hi guys!

I haven´t installed the plugin yet, but I would like to know if can you add some functionality (willig to pay for it if it is necessary).

We want it to be possible for users to ask questions directly to specialists or experts of different areas. These specialists would be other buddypress users which need to be notified when someone asks them a question.

Also we want only these specialists to be able to reply to the questions they receive, and that the user that originaly asked the question, to be notified when their question is answered, just like on this forum.
