create e-commerce site with in-built cart pointing to paypal

I need a site created which will feature a shopping cart that is hosted on the site. It needs to be able to have multiple selections like, colour, size, QTY, etc... also possibly feature discount by quantity. Once payment is required, checkout, then it diverts to PayPal, but would be good to have a checkout page hosted on the site without leaving, but payment is through PayPal. The background needs to be gold, The client already has a design and the key elements are gold and the lace feel. The logo cannot change. They layout that I have attached in the link below can change as I mentioned the key elements will have to be the logo, the gold background, and the lace/masquerade theme. [login to view URL] This link contains their site layout and even their shopping cart layout and their product page layout with the options they need. This cannot really change, the design or layout of where these options are located on the page is OK to move about where ever you see fit. They sell wrist bands, and they need to be able to have the user create their own design with text and then submit that design with their payment. ****************************************************************************************************************************************** Please only reply with ecommerce links and zip/rar files with images of carts and relevant ecommerce site you have created in the past. Please make sure that any links are actual working sites. ****************************************************************************************************************************************** Please note that I do not want an open source software solution like osCommerce or Zencart, as I know my way around OpenCart but is not what the client wants. They need to be able to have a CMS or backend where they can add the products themselves.
