Upload products to major ecommerce platforms

I am looking for a freelancer to help me upload products to Amazon & Ebay. These products are for industrial use, and I already have the necessary product images; I just need someone to help me upload them to the platform. I’m looking for someone with knowledge of the Amazon platform and experience in product uploads. The right candidate will have good attention to detail and a deep understanding of the Amazon/ Ebay platform to ensure that my product uploads are successful. Scope is considered for about 100+ different products, same products on both platforms
