Admob integration into an Android project (Interstitial and Banner)

A soundboard Android app requiring admob integration. Interstitials to push at various time frames.

The project is based on a project from Github. When changing the package id the app reports errors, so not only is admob integration required but the app must be functioning with my package id.

I can supply web address of the project to see if able to complete work before agreeing a price.

Thank you for your interest.
