Amazon Ads Book Marketing

I have partnered with an author of a book series and I want some guidance on how to run an amazon ad campaign. The goal is to find some profitable ads and let them run for as long as they stay that way. I want someone with lots of experience doing this to help show me how it can be done well and with as little money wasted as possible. If this works out and you like running campaigns, there would be an opportunity for a position where you could participate in a profit share model of future ad campaigns with other authors. For this application, be sure to include relevant experience of books you have marketed in the past, the results you got and some insight you can bring to the table. Thank you and look forward to hearing back.
