Build Refer a friend affiliate marketing tool

I am looking to develop an affiliate marketing tool for my wordpress e commerce site that works as follows: - customer A visits site - customer A clicks on affiliate link - Customer A logs into site (if already logged in proceeds to next step) - customer A is supplied with foll options to share (pls see attached picture) . Facebook: pick a friend (uses facebook API to show Customer A's friend list) . Twitter, facebook post on profile . Email: send email directly, or scan contacts through hotmail,gmail etc (can be done easily for example through plaxo plugin) . copy past affiliate link Every customer is given an affiliate id. Once a refferal (Customer B) clicks on the affiliate link posted by the customer A, he is directed to a specified page. If Customer B completes a given task, for example . makes a purchase . fills a specified form Customer A is credited with a specified amount . Amount X if Customer B makes a purchase . Amount Y if Customer B fills a form Customer A should be able to view at any point of time . Person to whom invitations by email have been sent out and status . Credited amount because of successful referrals Once Customer A would like to utilize its balance, she emails us and we produce a voucher for her. (this functionality already exists in site) The attached picture is from www.shoedazzle.com. The above describes the functionality that shoe dazzle offers to its customers. You can check out the shoe dazzle website to see how this works. I am using the wordpress platform for the e commerce site. This referal plugin must integrate with the sites front end membership sections (different from wordpress member) to store customers login details. Pls message for any additional questions. Please study the requirements and send me a quotation. I will approach suitable candidates to set up a skype call to discuss project. I am an experienced and 5 star rated Odesk employer (Tradelux LLC)
