436850 Custom affiliate script needed

Hello, I need to have a 2-tier affiliate script written for me that works with MySQL. It will functional like a typical affiliate script but should also have the following: 1. After an affiliate signs up, they should have an area where they can enter email addresses of their friends and an invite will be mailed to them to come and shop. 2. I would like both the affiliate and the people who click on the link within the invite email to be greeted by name when they are on the site. 3. There needs to be a way to set a start date and an end date for when the affiliate code will work. Please let me know in the PMB if you have any questions. Thanks, Jennifer
