1Shopping Cart Expert Required

Looking for assistance with making changes to an existing 1Shopping Cart account. The things that need to be set up are as follows. I have a list from people who signed up as affiliates before and now want to ‘assign’ most of them to the new program. I then want to emailing existing affiliates with their unique affiliate tracking url to the new landing page so it will track their sign ups (for a free teleseminar) so when they make a sale I can assign the affiliate payment. I need to know how to set up a shopping cart with 1 product that will be available as a 1 pay and 3 pay in both £ +Vat and $ (no tax). i.e. 4 variations of buying the 1 product. Is it possible to do multi currency? I also need to check that sign ups to the free call are put in a separate mailing list so I can send a campaign to them from 1SC. Work needs to be completed by Wednesday 19th May 2011
