Music: Integrating Garage Band+Text Templates+Testing

Must be able to take snippets of sound bites from Garage Band recording that I make into a template and then test the final template adding music transitions from public sourced music. This is creating dozens of different "Coached Workout" for runners for our company UPBEAT WORKOUTS, the iPhone app. I will provide the Garage Band voice recordings, you will cut and paste them into a template that I will provide and then calculate total time and submit after testing back to me.
