I want an automation based Dropshipping site.

Now I will provide a brief description, and you will elaborate on it in more detail. The website will be based on the concept of drop shipping, combining the functionalities of Walmart and eBay.com. It will allow users to purchase products from these platforms and list them for sale on Amazon. However, these processes need to be automated. For instance, when a user enters a search term or a category during product research, the website should simultaneously search both Amazon and eBay for the same product. The results will be matched, and the site will request the sale of products suitable for listing. A web crawler will be implemented, and an API will be used for listing purposes. The website will include an order section, an interim storage process, a product tracking system, an order automation process, and report analysis. There are many more details involved. I would like you to provide a more professional and comprehensive explanation based on this text.
