Quick simple php additions

I have a membership script that needs some simple modification... It currently has a basic membership sign up option, you can add links, pages, make it free or paid for, and has a basic affiliate program built in.. I need some more features expanded upon and added... *Third Party Autoresponder integration with the sign up section * Affiliate program to allow more than a paid one time, so the affiliate can earn commission on monthly membership etc.... *Have the script take Euros, Sterling and Dollars in Paypal (currently just dollars) * I would like the script to integrate with other third party payment processors like clickbank, [login to view URL], 2checkout etc This is the first simple stage of development for this script, there will be more, but this will depend on the quality of the work on this first upgrade... you can see a demo of the site working here... [login to view URL] I will sort out admin access for those that bid and wish to see more from admin side.. Please ask any questions when placing your bid.. payment is via escrow in full once the script is shown working on your servers. There will be NO TRANSFER of this script to other jobs you undertake, meaning that the script remains OUR ownership, and you cannot simply pass this off on other projects... Look forward to your bids.. Martin
