44922 Custom OSCommerce Module

Looking to emulate the "intelligent" autoresponder system of [login to view URL] for an OSCommerce website. Customer needs to be able to open an account simply by giving their email address and nothing else. From that point, the intelligent autoresponder will continue to send them email's about products in the store until they buy something. I need to check on what happens at that point, but my understanding is that after that they'll continue to get emails about various products, but NOT the one/s they've already purchased. Please explore [login to view URL] for a better understanding of what I'm talking about. This needs to be integrated into an OSCommerce website seamlessly with special attention to data modeling. I don't want the database populated with a bunch of unneccessary items. I've gotten bloated databases too many times in the past from shoddy mod "hacks". Please, experienced PHP/MySQL programmers only. For the winning bidder, there's likely to be more work in the future if we work well together. I already have 2 other PHP projects waiting in the wings for the right programmer.
