complete ecommerce eyeglasses website

I require a website to be constructed that will allow a customer to view frames and once choosing, progress to purchasing their optical lenses and other options and entering their prescription. Payment will be done offsite most likely with Paypal. The function of the website and layout would be similar to www.speckyfoureyes.com. I require a VIRTUAL TRY ON feature to allow the customer to try on frames (either using sample photo, own photo from a stored file, or use webcam to take photo). [login to view URL] is a good example as it is quite quick to use and glassesusa.com. Uploading photo from a camera is on visionexpress.com. It will be a new and fully constructed website that will include a home page, about us, FAQs, help, customer sign up and login, and reordering with existing prescription, etc. Bidders must be familiar with Prestashop as this is a requirement for this website. Highest priority must be given to SEARCH ENGINE VISIBILITY and SPEED OF THE SITE. Final constructed website should be usable in all major browsers. Other requirements are: Website to allow the easiest way possible to update,edit and add products(capacity for around 500-1000 frames) from backend side. Attached is a sample of the home page. Pages will follow graphic design and colouring similar to www.britz.com.au. .
