I need a freelancer to manage our Amazon and eBay PPC Ads

Edesia Espress is a UK online retailer of coffee machine accessories. We sell a substantial amount of our products on Amazon and eBay and have been doing so for over 10 years. We are wanting to work with a freelancer that can oversee our PPC spending on both of these platforms in order to achieve specific goals we have. We are diversifying onto other platforms such as Temu, so experience in additional platforms and Google Ads, would also be a bonus - but Amazon and eBay are the most important right now. We would like to work with someone that takes the time to understand the nuances of our business and does not simply set out to apply a one size fits all approach. Being fluent in English (preferably native speaker) is essential.
