Realistic GIF Animation for Marketing -- 2

I'm looking for a skilled animator to create a realistic-style GIF for marketing purposes. We're creating a wireframe for an app project and need four simple animations (gifs) to simulate some functionality. The animations will serve as basic elements within the wireframe. The total length of all animations should be about 15 seconds.

Ideal Skills:
- Proficiency in GIF animation
- Experience in creating realistic animations
- Understanding of marketing-oriented content
- Ability to translate concepts into engaging visuals
