Bold & Vibrant Business News Template Design

I'm looking for a designer who can create a bold and vibrant PowerPoint (PPT) template for our business news, as well as YouTube thumbnail templates for our channel. These designs will be used repeatedly in our video production work, so they need to be visually coherent and adaptable to different content.

PPT Template:
- Should include text placeholders with bullet points and image placeholders.
- It needs to be designed in a way that allows us to easily convey our business news with professionalism, yet maintaining a vibrant and engaging aesthetic.

YouTube Thumbnails:
- The visual elements of the thumbnails must include attention-grabbing headlines, high-quality images, and a clever use of bright colors and contrast to stand out in viewers' feeds.

Ideal skills and experience for this job include:
- Proficiency in graphic design software (e.g., Adobe Illustrator, Photoshop, PowerPoint)
- Prior experience in creating corporate templates and YouTube thumbnails.
- A portfolio demonstrating bold and vibrant design work.
- Understanding of visual storytelling and brand consistency.

Please provide examples of your previous work that align with this project.
