Amazon / Ebay UK Private Label Product Research

I am looking to hire someone to find profitable sellable products for Amazon private label. Also if theres is an opportunity then also want to sell the products on Ebay as well. Looking for someone who has already experience of private label on both Amazon and Ebay platforms, and able to demonstrate and show the experience will be highly recommended. Looking for products that are not just copied from other sellers as require some differentiation and uniqueness in order to have a good sale. Ideally looking for atleast 3 products for Amazon so that can decide which product to pick in initially. Ideally also looking for someone who can help scale sale on Amazon and Ebay platforms. Can start with task based approach and with right candidate can go for long working relationship. Even can for complete A2Z approach for amazon private Label. Flexible with the categories and budget at this stage but can discuss further when connect on then call. I am UK based so looking for UK marketplace initially. Also ask if have any question please.
