Page Specific Member

I’m working on a grade school site and would like to have each teacher have their own page. Allowing them access to do whatever they want – add fieldtrip pictures, assignments, notices, etc. But only have access to their specific page only – not to other teacher’s pages nor the rest of the school’s pages. I’ve seen the ‘Members’ plugin, it comes close, but I don’t see it allowing for a specific page (or even a post). Any suggestions?
