Marketing videos for Game release

We are releasing a new game and need some marketing content to show on our Youtube channel and also social media. For these pieces of content, we also need an animated mobile device to show the gameplay and various game screens - this device will feature on all the marketing.

Deliverables would be :
- Animated mobile device showing gameplay and various game screens
- A 1920 * 1080 video (30 seconds)
- A 1080 * 1080 video (30 seconds)
- A 1080 * 1920 video (30 seconds)
- All the working files and project files

This would require someone who can input into the design to improve on our briefs and also some rounds of amends.
