Hotspot Login integrated with Radius Manager 3

Require an account creation page for a Wireless hotspot. The process would be as follows; 1) The user enters their mobile phone number into the login page (this will be their username); 2) A random password is generated 3) possibly using PHP MyAdmin, the mobile number (username) and password is injected into the MySQL database of Radius Manager 3 via TCP/IP along with a pre-defined limit for daily usage. 4) an email is sent to an SMS gateway (mailto: <mobile no.>@[login to view URL]) with the password included in the email body (this is the only way a user can access their password) 5) the user is redirected back to the original login page.
