Professional Thumbnail Design for Tutorials

I'm looking for a designer who can create professional and corporate style thumbnails for my tutorial videos. The thumbnails need to include cutouts of characters or people, and they should be visually striking yet clean and minimalist.

Ideal Skills:
- Graphic design with a focus on YouTube thumbnails
- Experience in creating professional and corporate style visuals
- Ability to incorporate character or person cutouts in designs
- Understanding of YouTube's algorithm and mobile optimization

Please provide examples of similar work you've done in the past.
