Check Wholesale Website for new Costumes

Hi we need someone to check a wholesale website with costumes and add any new ones we don't have. I will provide an Excel spreadsheet with a list of our current 285 products from this brand. You can check photos on our website if you want to be sure, but each item has an unigue productcode. Highlight any rows from products we have, then on sheet two add new products in similar format. productcode, name, description, and price (2.5x wholesale) must be added for each new product. Photos must be saved to match productcode name. Many costumes have sizes which will be entered on sheet 3. A couple sample swill be provided so you can see how they are entered. I'm guessing about 100 new products, will need to be added but I am not sure.
