Hello,
The concept that you are describing, would be an affiliate website with product info display through a data scraper.
To track and change affiliate ID, you would need to have product feeds (XML or CSV) from sources such as CJ or Linkshare and also the data would be much more accurate than scraping. We have already done a couple of projects where the product data comes from external feed sources.
I will appreciated if you arrange a meeting with you. so we can discuss the project in brief along with the timeline, price and support.
Looking forward to your reply.
Regards
Prasun
