How can I track orders from each ambassador's landing page?

[gmm314]

We're in the process of launching an ambassador program. Each ambassador will have a personalized landing page with their favorite products will be listed on the page. I'd like to have the following functionality in place: 

• Visitors can view each ambassador's landing page and add items to their shopping cart directly from the page
• When visitors complete their purchase, the sale is automatically attributed to the ambassador's landing page

I've looked at several affiliate/ambassador apps but they seem to be either low-budget, or they don't actually allow purchasing from the landing page of each ambassador. Any ideas would be appreciated.
