client/project management with doc mgmt for design firm

Would like to build a secure site that will allow our clients to login and review work, make comments, etc. - Site would need to have user management capabilities so that clients can be given unique user/password information - Site should only allow access to information by client/user - There needs to be project management features so that a client can have multiple projects that are separate. - Site will need to have document uploading and version management features to allow designers to upload rough work, get feedback from the client on the site. The site should notify the client that new work has been uploaded and is available for review and should also let the designer know when the client has reviewed the work. The versioning should tree by project so that client/designer can see progress of project. Additionally this area will allow clients to sign off on work for approved final designs. This is a rough idea of what I would like to have and I am certain that there are areas/ideas that I am missing and welcome any and all suggestions. Site should be coded in PHP and use MySQL.
