Comprehensive Amazon Category Listing Tree

I'm looking for a freelancer who can create a detailed category listing tree for Amazon. This tree should include:

- 3 Main Categories (Departments): I need all three of Amazon's main categories to be included in the tree.
- All Sub Categories: Please ensure that every sub-category within these main categories is included.
- Depth: The category tree should go as deep as possible, including all levels of sub-categories.
- Products : In each category and sub cat i need the keywords (products) that are in them. Not all the products, only the title of the products that are different from the other in the cat or sub cat. In order to see which type of products are in each categories and sub cat.

My main issue is i don't have access to the Advertising API since i'm not an associate (affiliate) on Amazon so i'm looking for someone who have it.
