Concept video for App

We’re looking for a company that can help us create a concept video (music+video that’s 30-60 seconds long, we’ll record the audio in Swedish later on) explaining the key concept of our application, full description of the application and service will be given to the winner. We have no concept story written or audio tracks recorded yet, so we’d also like help to write the story and the audio punch lines – you provide us with a first idea and we’ll give you feedback until we’re satisfied. Once the story has been decided we’d also like you to produce and compose the video we’ll record the audio afterwards and you’ll add that to the video. If you do have a good native English voice or are fluent we’d be willing to consider using your audio tracks for explaining the product connect. What we like is something that looks like this.
