Create 2 different motion banners 15 seconds each

I need 2 separate banners, each 15 seconds long with a different motion graphic. I have attached an example so you can get an idea of what I want. But keep in mind this is just an example. Do not do the exact same style because this belongs to a different company.

Banner Specs:
5624x90, 25fps, .MP4, @H264 / Color space REC 709

Your task:
1. Come up with the idea for the 2 banners (2 different companies and niches). I will provide the logos and text, but you will have to decide how to present all that in the banner.
2. Be willing to provide 2 different versions for each banner that I can choose from.
3. Complete this with 12 hours or so.

To be considered, provide examples of similar work you have done in the past.
