Create App Instructional/Explainer/Promo Video

I need the app to be featured in the video, with demonstrations using the app. It is a video about an app, so it is important that usage of the app be inside of the video. The app is a Business GPS tracker / Communitcator for Employees in the field. Such as delivery / Salespeople. Need a video showing a manager getting a phone call about the whereabouts of his employees that are working outside of the office. He uses the app to gps their location. He communicates with them in the app. They respond on the app. His face of relief and relaxes after.
