64235 Custom Affilate Program Script

I need an affilate script for a new stock alert program. The script must be able to track affilate signups, and allow "member to member" and "member to company" subscription payments through PayPal and Stormpay. The script will be able to handle sending out large voulmes of personalized e-mail messages to subscribers. The script will need to be able to send e-mail messages to two different groups of subscribers, free subscribers and paid subscribers. Free subscribers will be able to upgrade to Paid subscribers by making two subscription payments, one to the subscribers referrer and another one to the company, once both payments are made the free account will be upgraded to Paid and the member will be moved from the free e-mail list to the paid e-mail list. The paid e-mail list will provide a higher number of alerts. Alterts will be entered into a form in the admin area and then sent to the selected list by admin clicking a submit button. PHP and MySql
