Custom design, installation and configuration for prestashop ecommerce

The project consist on a custom design (not a template) for an ecommerce website, logo included, at the begining some rough draft, both for the logo and the design, then one of them will be approved, 2-3 would be enough. Prestashop will be used for this project, it is an opensource code software similar to oscommerce or zencart but newer and with lot more features. The site will sell sunglasses online. The name for the website is not yet defined, however it will be known prior to start the work as its important for the logo. We will use default options in Prestashop, so programming will not be needed. Just custom configuration. Regards.
