PowerPoint Rebranding and Update

I need a freelancer to rebrand and update my internal training PowerPoint presentations while retaining most of the original content.

Key requirements:
- Visual design refresh
- Formatting and layout improvements
- Incorporate brand elements like logo, colors, and graphics aligned with the company’s color scheme

Ideal skills and experience:
- Strong PowerPoint design expertise
- Experience with corporate branding integration
- Attention to detail and creativity
