Looking for a Content Management System (CMS) for a particular website project, please read if you can help!?

Hello all,

I'm aiming to build a website using a CMS, of PHP/MySQL format. I'm familiar with Drupal but I think that could be too complex for it; it seems to me that it will only need a simple CMS.

The aim of the website is to be a simple one explaining what the company does. But a login system is required for clients who wish to obtain particular information from us. So for example, the client might log in, click a request information button, fill in some text fields and tick a selection of check boxes that are relevant. This then needs to be saved in a database and email our company a copy of it.

We need a login system for ourselves to obtain this information via the website, and respond to it by attaching a PDF document or something similar.

The hierachy may end up like a forum, with Admin (being myself), moderator (the employees) and users (the clients).

I must also stress that it needs to look simple and jargon-free for both our clients and employees.

Thanks very much!!
