Implement a custom e-commerce solution based on an open source store platform

Set up an online store by customizing an existing e-commerce platform (osCommerce, ZenCart, Magento, etc.) with a professional-looking skin and certain programming features described below. This store will not actually be used for real sales. Instead, it is intended for marketing research. As a result there are certain features that are non-standard and require modifying the open source e-commerce code. A few examples of these features are listed below. * the checkout area accepts credit card information but does not actually process the card (pre-order payments) * products should display different versions of the same product to different visitors (different description, different price, shipping cost, etc.) in order to determine which version of the product sells best. (Also known as A/B testing: [login to view URL]) * Google Analytics integration * detailed reporting on product versions, integrated with Analytics information: admin can determine which version of the product sells best and which marketing campaign (from Analytics) generated those sales * rich CMS (content management) capabilities for the site that allows the admin to create content pages (About Us, How it Works, etc.) as well detailed product description pages. The store will list only a small number of products (with multiple versions) and so the focus will be primarily on information about these products, rather than a large number of categories & items (which is typical of some e-commerce sites). See [login to view URL] for an example of such a site. I do not particularly care which open source e-commerce platform you use or which technology it uses (PHP, ASP.NET, etc.) or even if you develop one from scratch, but it is very important that the design looks clean, polished, and professional.

Also indicate the approximate number of skins / templates / layouts available by default and provide examples if possible.**
