State of the Art Online Store with advanced functionality

Please give me your bid for the following project: Create online store for looking glasses by "cloning" a site like [login to view URL] or similar. Users should have the option to virtually try frames by uploading their photo. Frames should be presentable in 3D images. Users should be able to order by entering their optical parameters (prescription). The system should be able to check if a certain frame is compatible with the specific optical parameters. Frontend should be extremely clear and easy to navigate. The Store Backend should be extremely easy to use even for non techie staff. We need a highly professional solution able to handle huge numbers of orders and with good interface to accounting etc. Maybe there is a ready-made ecommerce software , that can be modified. We are open to your suggestions. Thanks!
