Amazon store setup

I'm looking for an experienced Amazon store setup specialist to help me successfully set up a Basic Store. Additionally, I do have an existing storefront with Shopify that needs to be migrated. So I am looking for someone who has in-depth knowledge and skill in setting up Amazon stores and migrating existing storefronts. The individual must also be able to provide advice and recommendations based on their experience, as I am hoping to make the most out of this project.
