I am looking to build a service where I sell IP addresses. I already have Squid Cache (http://www.squid-cache.org/) set up with SAMS (http://sams.perm.ru/index.php?lang=english) for the account management. What I Need Done: I have many IPs. If I make an account in SAMs it is available with all IPs. I need it so that each account only works with 1 IP. To make an account, I login and put in the information manually. This is the part I also need automated. Specifically: - User subscribes via Paypal and gets IP/account set up. (only 1 IP per account) The information is emailed to the user. - When user cancels subscription, the account is disabled and the IP is now available for a new user. Requirements: - Programmer should be familiar with Linux, Squid Cache, SAMs, PHP, and Paypal.
