What would be the best way to implement video ads for a Flutter app?

Currently making a video storage and streaming application. Right now I am trying to add ads to the application. What would be the best way to facilitate video ads for the app? I know that there is a google_mobile_ads package, but due to the guidelines of AdMob, I cannot show multiple video ads in a row. I would like to do something similar to YouTube where a series of 2 ads are shown to the user (in my case, 1 ad for every 30 minutes of content).
