Reserch for products for New amazon store

I'm looking to create an Amazon and Walmart stores i I will be selling every ítem. so I need to interact with suppliers to get the items I wish to list for sale. Additionally, I will be setting up a system to monitor my inventory levels, ensuring adequate supply and avoiding any ordering complications.

I have some basic knowledge of creating an e-commerce store with some experience from a recent project, but I am looking for someone who can help to create a comprehensive setup where customers can shop.
