Amazon co.uk API integration with custom webstore system - urgent

Hi We are in need of integration of our web store with Amazon.co.uk. The store which is based on software not commonly known will be our central stock management and order fulfillment channel. We want the integration to proceed it number of phases . This particular job is for phase 1, however we would like to work with the same person on the later phases if we're happy. Phases (in order of urgency) : Phase 1. (VERY URGENT) To pull order details from Amazon and input them into store via store's API (which is quite sophisticated) The process must be customizable, i.e we must have the possibility to fine tune mapping of some fields. We will be using multiple SKU's for single products in the shop, so SKU's from orders will be remapped onto store's stock ID's - template for this remapping must be customizable as well. Phase 2. To synchronize stock levels on Amazon with the shop Phase 3. To allow for Amazon listing creation based on data pulled from the shop. We prefer web based system. Any programming technology as long as it works - they're all the same to me. Open code only please. We are seeking very experienced Amazon / API programmers ONLY. Ideal person will be not only a serious pro but also enthusiastic, friendly person and will not try to take advantage of the fact that I know nothing about programming :) Sense of humor will definitely be an advantage too. Please write "AMAZON IAI" in the first line of your response so I know you are not a bot. Thank you
