Interactive PowerPoint Revamp Needed

I have a solid educational PowerPoint deck but it still feels like a sequence of static slides. I’d like you to elevate it into an engaging, modern-looking experience that I can easily edit later on.

Here’s what I’m after:

• True interactivity: build in short quizzes or polls at logical break points so learners can check their understanding, and embed a few carefully selected video or audio clips directly in the file. Everything should run smoothly inside PowerPoint—no external links that might break.

• Visual refresh: give the presentation a modern, sleek aesthetic—clean typography, balanced whitespace, subtle motion, and cohesive iconography. I’m not looking for loud colors or over-designed elements; think contemporary, professional, and easy on the eyes.

• Future-proof structure: keep slide masters and layouts organized so I can add, remove, or rearrange content without breaking the design or interactive components. Document any custom fonts or add-ins you use and include brief notes on how to update quizzes or swap media files.

Deliverables
- Redesigned PowerPoint (.pptx) with interactive elements fully functional
- A short “maintenance guide” (one-pager or annotated slide) explaining how I can modify content and interactivity myself

Once I supply the current deck, let me know any assets you need and your estimated turnaround. I need this returned back to me no longer than 48 hours as I have to present this in 4 days and will need to study it before doing so.
