Corporate PowerPoint Re-Design Expert Needed

I am looking for a PowerPoint expert who can help me enhance the visual appeal of my existing presentation. The presentation currently has about 490 slides (some are duplicates), and I need someone who can transform it into a more professional and corporate style.

Your tasks will include:
- Implementing visual enhancements throughout the presentation
- Ensuring a consistent and appropriate corporate visual style
- Making the slides engaging and attractive but still professional

For this job, you should have:
- Proven experience in PowerPoint design and re-design
- Strong understanding of corporate visual style and design principles
- A portfolio of previous work that demonstrates your ability to make engaging, professional presentations

You are NOT required to redesign PM4 files.
Do not add video animation, or GIF images.

You need to provide a few slides indicating your proposed styles; I like soft colors.
You may provide more than one version.
Please DO NOT Call me.

I look forward to seeing how you can help me improve my presentation.
