@LsVtechTurbo95, the Corona community forums are here to help you on a best effort method. Corona Labs cannot write your program for you. If you wish to hire a Corona Developer you can request a quote in one of our sub-forums dedicated to hiring Corona Developers. See: http://forums.coronalabs.com/forum/586-corona-jobs/
There is an expectation that you will try to also help yourself. All advice that’s been given to you on this topic has been sound and has been given to you by multiple people. I don’t know why you and your programmer are having difficulties implementing this. You have to take some responsibility yourself. No one on this forum has access to your AdMob account (nor should they). By refusing to provide information from your console log (and having been shown twice to the tutorial that teaches you how), there isn’t much anyone on this forum can do for you.
I even provided you a 100% complete working AdMob sample main.lua. It’s job is to show a screen and show an ad. It’'s up to you to adapt this.
We have very specific forum rules and expected behavior from community members. Please make sure you read and understand these rules before you post to the forums: http://coronalabs.com/blog/2013/04/02/corona-forum-rules-and-guidelines/
