Shopping Cart and design template installation

We want to build a new website which will sell electronics parts. We already have our product database on csv file. We need someone who can install a shopping cart and design template for us. We will upload products by our selves. We already have 1 website selling products so we are very familiar with using shopping carts. We will prefer to use the shopping cart you are familiar with to do things easier for you. Some Most important features that this shopping cart (website) must have; - Invoice Adjustment ( after customer paid for an order and if they request any change in their order details etc.) - Discount Coupons and promotion options. - Order / Product / Promotions etc Excel/CSV IMPORT and EXPORT ( this is very important!) - Multi Currency - Automated Google Base submission ( this is very important! ) - When uploading products to site using excel file, to have columns in excel file to specify, "in site search" and "search engines" keywords - Product Price levels - Admin users and user usage limitations. - PayPal and 2checkout. - Inventory management. ( restock levels for each product individually. We should be able to set reorder point and restock levels for each product on excel file while we uploading the product) We already have the domain name and we are ready to buy VPS after consulting with you. You will be bringing the template and shopping cart. If you are interested please make sure to give us list of websites you have already done when you are contacting to us. If you can successfully finish installing the shopping cart and template we will have long term business relationship with you and you will be the one who will do all the future upgrades for this website. IMPORTANT "Payment": If we accept your offer we will pay you "RIGHT AFTER" the completion of successfully installation of shopping cart and design. We will NOT pay any amount in advance but we will pay it all to you the moment you successfully finished this project.
