Enhancing Corporate Powerpoint Template

Need a corporate Powerpoint presentation that provides a sales team and other departments with a template to easily work with and include the following slide types:

Essential Slide Layouts to Include
1. Title Slide (main opening slide)
2. Section Divider (for transitions between topics)
3. Content with Title (standard text + bullet points + image placeholder)
4. Two-Column Layout (text and image, text and chart)
5. Full-Image with Overlay Text
6. Data/Chart Slide (bar, line, pie, etc.)
7. Comparison Slide (side-by-side features, pros/cons)
8. Quote Slide (for impactful statements)
9. Agenda/Timeline Slide
10. Process or Flow Diagram
11. Contact Info Slide
12. Closing or Thank You Slide
13. Map layout (for geographic data)
14. Video placeholder slide
15. About Us / Team / Values Slide
16. Case study / testimonial layout

I need elements like the logo and visuals locked so people cannot play with the style at all. I provided a few slides from our current template and don't want to stray too far from it.
