Arcade Game App Purchase & Ad Integration

Hi, I'm looking for a professional who can assist me in purchasing a ready-made Arcade game app. This app needs to comply with Google Play's policies. Post-purchase, I'm expecting you to integrate ads from both AdMob and Unity Ads. Additionally, the app will require maybe a minor modifications before the ad integration. Ultimately, I need the app to be fully prepared for upload to Google Play. Please let me know your availability for this project.
