Create an Animated Promotional Video

I require a high quality Promotional Trailer for a factual film I am planning to do in the future. It will be used to pitch the proposed film to funding bodies and investors. The trailer needs to be exactly 60 seconds, and has to come with music and sound effects. I’m looking for a trailer that would look something like this.
