Product listing on Flipkart and Amazon

Hello, I'm looking for a freelancer to help me list products on Flipkart and Amazon. I'm selling hardware paint electronics products, for which I have product details and images ready, and I will manage shipping myself. My goal is to create listings that will optimize sales and increase my online presence. So I need a turnaround time that's fast and effective. Any freelancer who can help me achieve this and provide top-notch service will be an ideal fit!
