I will integrate google admob ads in your android app or game. I can integrate both banner and interstitial ads. I will integrate the ads based on your suggestion and requirements but I will guide you also about ad placement of ads to enhance earnings and to prevent ban from google. I will charge 5$ if you have 1 to 5 Activities (screens) in your app/game. 10$ if you have got 6-15 Activities and 15$ if you have 16-40 Activities.
