What kind of web application should I use to make a private information tool?

Question

I am trying to find a tool where me and my co-workers can have an structure like this:

(Web app)
    - State Foo
        - Business A
            - Project 1
            - Project 2
            - Project 3
        - Business B
            - Project 4
            - Project 5
    - State Bar
        - Business D
            - Project 6
            - Project 7

That we can use to keep track of the projects we are working on; where every 'Project' is just a place to post the progress of said project with text, styles, images, attachments, etc., and is only accessible to a certain 'Editor' and a certain 'Viewer' (with the corresponding permissions). It also must be private, so only someone with an account can access the content, a certain 'viewer' must only be able to see projects he's allowed to and all the users can only be created by a site admin.

The only thing that came close to it was using a forum app (phpBB); it has an structure very similar to what we need and has most of the features we expect, but it lacks the option to create users manually.

Is there another app that can fit (or at least come close) to our needs?

While I am not quite sure I understand your requirements, have you looked at popular web-app Trello?

The hierarchical levels of organization in Trello are:

• Organization (basically the whole project)
• Board (basically a screen, a view; an organization can have several boards)
• Lists (a vertical list of cards, a board can have several lists)
• Cards (a small item with a title; it can be opened and contain text, pictures, comments etc.)
• Tasks (a task can be checked off or not; a card can contain one ore more task lists)

You can make users members of organisations or boards (controlling access). Every card can be assigned to one ore more users.
