Browser app to Monetize + add AD breaks

Hello, I'm going to need a software or a script which will make changes on a youtube channel. Program will automatically monetize and add AD breaks to all videos in a Youtube channel one by one on a browser. - Ad breaks will be as long as the video length with 8 minutes intervals - It could be a windows program or iMacros script or any other possible way My budget is $30 Thank you!
