Amazon Advertising for KDP Books

I am looking for an amazon advertising specialist.

We sell coloring books for kids on Amazon and need support for Amazon Advertising. ACOS and Sales are less. We tried some tools like Adspert or Perpetua but it dont work very well. All in all we have around 80 books that need to be managed. Similar books can be advertised in one group.
Since some time our ACOS increased dramatically and adspend too. We need someone who do optimizations and manage our campaigns in future, create new campaigns and do everything to save money and increase sales for us.

We are working on the German KDP market and have a Vendor Advertising Account and a KDP Advertising account. you can use both.

Maybe you can do a good strategy for us and our products.

Please send me a concrete offer with your salary and estimated ---------- future we will expand on google advertising too. so please alos be a specialist in Googlge Ads

Thanks for your application.
