Client profile/status page

I’m trying to create a front-end user interface where my clients can log in, and see the status of their current account for the services we offer. The status would have many specific fields of information that can change from time to time. The displayed front-end content would be “read-only”.

I’m also looking for a back-end interface so I can manually enter (or import using a data file) information on all my clients and their statuses.

Is there such a a plug-in that would accomplish this?

(I’m also using Optimizepress 2.0 if that helps any)
