Design and implement eCommerce website, extensible

Need design and implementation of a single-item-offered-per-day shopping website. Similar sales model to Woot and Group Coupon. Standard eCommerce web-building techniques apply. Multi lingual interface. Offer content specific to user's geographic location. Hold user registration data, product serial codes, keep track of valid period for coupon offers. Do NOT need genuine shopping carts, but do need to hold transaction history. This project will be the first of several related and connected IT projects, so we are looking for someone who we can form a long term relationship and work with continuously. If you are looking for a steady stream of work, can deliver quickly and have other technical skills in your organization, then you may be able to apply them for us in the near future also. Future related projects will include extension to accessible backend for partner businesses to operate via web or RIA, push delivery of coupons to mobile phones, and B2C video conferencing enabled via web and mobile. Technical requirements: - All website text must be referenced through XML files for extension to non English language versions. - All graphics with text must also support a similar versioning system. Ideally, we want to be able to use English version graphics as a default, and have scripts override the default with specific language version. But if you have another solution, we are open to suggestion. - All files must be Unicode or UTF-8 compatible. - HTML & AJAX solutions preferred, but PHP, Flash or FLEX solutions will be considered as well. - Layout of page must be friendly to vertical scrolling (for later extension to mobile platforms). We are accustomed to working with non-native English speakers from a variety of locations, and the intended market for this project is not USA. Please do not be afraid to ask for explanations if anything is not clear. If interested, please reply with portfolio of projects already completed, for review and reference. Should be able to start project within 1 week. Time frame for first milestone is 2 weeks later.
