Build an ecommerce store with functionality like uline.com

We are in the shipping/packaging supply business and are looking for a complete ecommerce site with many features very similar to uline.com. We are thinking that Magento Go would we a good shopping cart for us. VERY IMPORTANT - All sku's/descriptions etc. needs to be entered into the system. So that once the project is finished there is nothing we need to do on our end except to go live with the site. We are on a schedule and need the site to up and running as quick as possible. Would be great if completion date is within 30 days. We need most items to be displayed in the table format. Here is an example of the table format we are wanting. [login to view URL] Different sku's would most lileky to have a different header in the tablet. Again, please refer to [login to view URL] for an example of the different headers needed. Once a buyer selects the add to cart button we want them to stay on the page so they can add more sizes without being sent to the check out cart. When they do select the item we would like to show the items going into the "smart-mini-cart." Here is an example of what we are referring to. Once you add the item to the cart it shows the item going into the cart. [login to view URL] The shipping calculator needs to be integrated with our with our supplier/drop shippers calculator. Store needs to be set up with the following but not limited to: - Facebook and Twitter. - Google Analytics - Payment gateway needs to be set up. - Search Engine Optimized - Mobile/Tablet Friendly version - Easy to use and maintain Ebay Template needs to be developed. All work must be of the highest quality. The team or web developers need to be experienced in Magento development and all the web technologies especially PHP, JavaScript, HTML5, CSS3 and Search Engine Optimization among others. We would need to see references of previous work too.
