hi, i am experienced android developer and understand your requirement. i know how to add any mobile network ads like admob, airpush,leadbolt, tapjoy, startapp etc. so it is easy for me to add the admob ads successfully without interfacing the performance of app. you can check my portfolio in which i work for airpush ads too on freelancer. so which type of admob ads you want to add banner or interstial. i can do the other changes too in graphs.
So please contact me so i can start now and if you have any questions feel free to ask...Thanks
