eCommerce solution

We are a startup and we want to introduce new, innovative product on the market. We need a e-commerce web solution preferably based on one of the existing e-commerce platforms. Since this new product is highly customizable, the solution should include fancy and enhanced but easy-to-use 3D product builder in a form of wizard. It should work seamlessly on desktop and mobile web browsers. The other requirement is the integration with ten most popular e-commerce platforms.
Generally, the look and feel is expected to be very attractive and intuitive to the user.
