User specific content Is it possible to show specific content or an entry for an individual user?

Here's what I'm trying to achieve: 

A logged in user make a request to receive information on a particular service. An administrator then reviews the request and creates an entry specific for that user - whatever is contained within that entry is then displayed on the users dashboard for them to view.

How would I go about achieving this?

Thanks!
Using the example in your comments, a simple solution would be to create a "Potential Jobs" Entry field and assign it to the Users field layout.

Whoever is doing the manually checking to find a match between tradesmen and clients would assign entries to that field that match the requirements.

The front-end user's dashboard would check that field to see if it has any entries in it and display them to the user.

You could probably get more elaborate with a Category field (that had Entry fields in it) if you want to group by more fine-grained details.
