Woocommerce Customization

Need to give discounts for the bulk purchase of products according to the Quantity. For Example - If they purchase a 10 Pcs of a product , there will a % of discount, if they purchase 100pcs then there will be different % of discount. The % of the discount will vary according to the product and quantity of the product. That is for example Mobile cant be purchased in bulk quantities.. It can be small numbers. But the Stapler pins can be purchased in huge amounts like 100, 200, etc. The Quantity and discounts can be vary from product to product. The stock should be managed according to the quantity purchased. There should be an option for bulk upload of the products with all the required fields including the corresponding image through an excel with these discount percentage. A draft example screenshot attached. This is just an idea.
