Add products onto my Shopify store with everything completed

I have on an excel sheet 2630 skus that will need to be added onto my website. They have different colors and sizes. So realistically it will be about 360 listings with the different colors and sizes. The following will have to be done on Shopify Title - I will provide the title Description - You will need to research the product on the manufacture website and other website and create your own unique description with all the relevant information (SEO bonus is a plus, if you can do SEO on this it will be a bonus on our decision to choose a freelancer) Media - You will need to download ALL the product/sku photos from the manufacture and add the photos *PHOTOS MUST BE 1000x1000 Pricing - Fill out the pricing, compare at price and also the cost per item (I will provide this information) Inventory - Fill out the SKU (stock keeping unit) and Barcode (ISBN, UPC, GTIN, etc) - (I will provide this information and EACH variant has their own sku, barcode, price, photo and etc) Check the track quantity if the excel sheet shows in stock and change the available quantity to 50 and if the item is out of stock then uncheck track quantity (this will be on the excel sheet) Shipping - make sure the this is a physical product box is checked Weight - I will provide the weight and you will need to fill it out Country/Region of origin - I will provide this information HS (Harmonized System) code - I will provide this information Variants - Again I have 2630 unique skus and it will need to be added. Since there are a lot of colors and sizes then the descriptions technically only needs to be done once and the custom variant information will need to be added (such as color, size price, quantity, sku and barcode) TO PREVENT SPAM PROPOSALS - PLEASE SEND THE FOLLOWING What is your pricing?
