73699 PHP Client/Admin Login Area

What I'm trying to achieve is multiple clients logging on to their own secure area where they will have the option of choosing additional pages within this secure area for approving graphics, mockups of their web site, etc. What I'd like is setup very similar to [login to view URL] When I sign on a new client, I want them to be able to go to "[login to view URL]" and enter their name/company, address, city, state, zip, phone, a username and email, then submit the form. I would like an email confirm sent to me to notify me of the new registration so I can logon to the admin area and setup the directory folder the new client would have access to. When I have updated their info, I would like an email confirm sent to them with an automatically generated password (if possible). Once this has taken place, the client would then go to "[login to view URL]" where there would be the login with username and password. I would like to have a "forgot password" option here. Once signed in, the user would be directed to their predesignated secure area. The Admin Area should have the capability to display/edit/delete the client information, as well as indicate the directory path. (see [login to view URL] use "admin/admin" as the login). I had purchased the Member Manager, but there were numerous errors, plus the client areas weren't secure - the script just directed the client to a particular url after logging on. This is one thing I should stress - the client area needs to somehow be secure.
