I need an explainer video for my app on Google play

This is the app: https://play.google.com/store/apps/details?id=com.mood.livewall

I need a video that explains first the two main features and also a few minor ones. The video should contain three Android phones in order to show that changes on one wallpaper are instantly seen on other phones using the same wallpaper.

1. Main features:
- editing a live wallpaper and switching between live wallpapers
- sharing the wallpaper with friends and communicating over them (anything a user puts on the wallpaper is instantly shown to other users of the same wallpaper)

2. Minor features:
- creating animations
- ading photos
- writing text
- taking screenshots
- making public wallpapers
- rotate, flip and resize objects
- long press to fill an object

NOTE: the video needs to show the actual application in action. The point of the application is that the livewallpaper can be edited and shared with friends. All changes made to the wallpaper by anyone of them is instantly visible on other phones. In order for this to explain to the user, three phones need to be shown in the video simultaniously so that instant sharing of changes is visible.

SECOND NOTES:

1. I will provide the complete script
2. I dont need any animations, I need a movie showing real devices. The hands operating the phones can be animated or real.
3. I need three actual devices, Android phones.
4. I need a voice, which explains the features
5. I need the three phones to be shown at the same time and hands working with the functions
6. You will have to download the app from the play store and login with FB account in order to show how it works

Please provide some info in your proposals, explaining that you understand my requests.
