'How to use' Promo video for new app

I just downloaded this toolkit online as I like the style and can therefore share it with you:

I now need someone to create the video for me using Adobe After Effects. This has to be a joint effort between myself and whoever takes the job as it is a demo for my app and I already know how I want the video to look... And I also know exactly how it works!
