Ecommerce website development - large project

Dear Contractors, I am posting this job on elance to see what kind of talent is out there and hopefully get a competitive price. Please provide details of your portfolio - all your recent design/ecommerce projects. The person I am looking for will build and then manage the website after it has been launched. Their prices will be cheap to update the site later and maintenance should be included. I am therefore looking for a reputed company that only uses the highest quality and most effective coding techniques. I run a successful company selling designer sunglasses, designer handbags, and other items to buyers in Australia. My suppliers are based in Italy and the USA. I have met with my suppliers and they have given me support for developing a global website, which has international distribution and will sell a wide range of products to consumers all around the world. I will need: 1) Ecommerce website; - This website should be very fast, scalable and able to handle heavy traffic IF and WHEN required. I have limited knowledge of IT, but I have heard that a cloud solution is best. - The websites' backend should be advanced, easy to use and also upgradeable easily. Advanced inventory management system, advanced CRM system, advanced marketing management (emails/newsletter) - The website should be linkable to amazon/ebay/google shopping and a template design for eBay consistent with the website will also be required; Also this process should be automatic, and also link the "quantities" available of a particular item to one central inventory management system. So if 1 qty of item X sells on the website, then the quantities across all platforms ebay/website/amazon/google should be reduced by 1 AUTOMATICALLY. - The website should allow for variant pricing across different countries. So in Italy I would want to sell for € [login to view URL], in Australia $AUD [login to view URL] and USA $USD z.zz. This process should be seamless and it should also automatically detect the customers country based on their IP address or other technology; - The website will have a VERY high standard of design and graphics will be crisp, original and also dynamic. - GROUP BUYING/DAILY DEALS technology - 48 hour deals section - Special sales for members only section - recurring payments ability - also need to be able to take priorirty membership payments on an annual basis. - Advanced merchandising- customers should be able to try on the sunglasses using a virtual mirror - the BEST and simplest virtual mirror technology will need to be applied. We will also want to incorporate 360 degree view techonology - we understand this is not expensive - but we will need to come up with an effective way to upload items. We would prefer to use a data sheet or some other bulk uploading methodology. 2) Content management system: - I will need a content management system, that is cleverly incorporated into the website, so that it provides users with information on the products/fashion trends etc. - Content should allow customers to purchase items listed in the article/content; 3) Very simple to use but advanced Shopping cart (credit cards, paypal and even bank transfer) 4) Advanced social networking functions - ability to login with facebook - activity feeds - wall section under each item for users to comment on the item using their facebook and more. 5) Iphone application - for shopping - link to credit card or paypal 6) Possibly required to link with suppliers systems; 7) High quality design.
