Dealer Login Area

We are a manufacturer who has dealers. I’m looking for a plug-in to provide a dealer login area that will accomplish 2 things.

1) I want to be able to provide dealer specific content that is only shown based on the username logging in. In other words User 1 will have personalized content that is different than what User 2 will see such as past invoices, current jobs etc.

2) I also want to be able to easily publish content that every login can see that I would not have to publish for each individual user. Examples: Current inventory lists, sales support literature and brochures, catalogs etc.

So in a nutshell I’m looking for a plug in that will allow users to login and view personalized content that no other dealers can see as well as content that I publish one time that becomes available for all dealers to see.
