Changes to an to online store design in asp.net

Updates to an online store design in asp.net store front Need to make a few Updates to my existing site. The site was created in asp.net store front and I need a company or developer that can complete this project as soon as possible and without breaking any of our current functions: - Need to be able to assigned attributes to a product: When we add product to the site we need to be able to add attributes to that given products. eg ( color, wattage, certification, glass finish etc) ideally we should have a list of attributes that can be assigned to each product. End result product attributes appear next to the description. See sample attached sample - Multiple Shipments (drop ship): Need to be able to split orders based on manufacture and order number. An order can have multiple items from different manufactures, we need to split the order base manufacture. Once it is split each new order should contain order number, customer id, bill to, ship to, item order, item name quantity - add Paypal express checkout as an option to our checkout page - (already included in [login to view URL]) add a form to enter reciprocal links: at this time we have a link page but links are manually added on an html file. need to create a form to simplify this process. Please send sample of your ecommerce work(asp).
