Product configurator and Ecommerce website

The website we are looking to create is a web-store that will sell products you have customized on the website. We would like to use an E-commerce solution such as Magento or Prestashop with a preference for the former. The team or web developers need to be experienced in Magento development and all the web technologies especially PHP, JavaScript, HTML5, CSS3 and Search Engine Optimization among others. The product configurator will be developed in HTML5 + Javascript (with a solution such as Raphael or SVG) as we would prefer avoiding flash solution. Of course a developer or a team with experience in those technologies would be preferable. This module needs to be fully integrated with the Ecommerce solution. We will supply the PSD files for the design. These are the main features and requirements include (though they are not limited to that): * Intuitive in-site application/service to upload imagery and resize/edit/distort then add text. This feature will be integrated in the product configurator * Shopping cart * Order process (with an option to save your address on your account) * Payment through paypal or credit card * Gallery view options * Social media sharing options from website * Account creation and management by the user * Searching tags, keywords and other data * Search engine optimization * Mobile/Tablet Friendly version * Promotion code in the cart * Ordering of gift voucher Backoffice (will depend a lot on the Ecommerce solution such as Magento): * Features to add products easily change prices… * Feature to configure the options of the product configurator (add, delete , update) * Feature to change the highlights on the home page * Management of the users * Management of the orders * Promoting some products in the view gallery or on the home page This website will require a wide range of skills and the team with similar experience in Magento and product configurator will have a strong advantage. So I will be happy to talk with any person interested to handle this project. As an IT guy myself, I will be able to help a lot on the understanding of the scope of the project and the features we need. Thanks I have a fully specification written and a partial product backlog that I can send upon request but as you can see i request the electronic NDA to be signed. Thanks a lot
