195116 Provide/Iinstall shopping cart

We need someone to provide us with an appropriate demo shopping cart or carts for us to review. Then install the new shopping cart of our choice to our website. We would like to keep our current website and keep the look of our current order form page. Our product, "live butterflies" requires the customer to choose "butterfly type", "event date", "quantity", "a packaging choice that may incur additional charges" "offer other optional items", then finally checkout. Our current shopping cart does this but our current shopping cart sends us an email and we have to process the credit card payment manually through [login to view URL] (our payment processor). We want to automate the payment process and have the ability to easily add new product categories of more traditional products. We would like the new shopping cart to: "have a backend control panel where we can view orders, payments, add new products, create invoices and packing slips, lookup customer previous orders, keep customer date, affiliate date, do email marketing etc. etc. etc. *The cart should allow customers to shop and checkout without creating an account. *After the sale the customer could be asked if they would like to create an account for their next visit. *the cart should process the credit card payment through [login to view URL] *the cart must be PCI compliant Our web hosting is with 1and1.com. Our web site is [login to view URL] We need someone who will be able to make additional modification as we need them to our website and shopping cart for additional cost to be determined based on the work required for each project. Please visit our website order form to be sure you fully understand our needs. Thanks, Karl
