Graphic designer to redesign Presentations

I am looking for a skilled graphic designer to redesign and format three existing presentations. This is a one-time, fixed-price project. The three presentations each have approximately 150 pages/slides. I need someone who can take the current content and upgrade the visual appeal, ensuring the decks look professional, modern, and consistent. The task: improve layouts, update typography, add relevant icons, and transform text-heavy slides into clean visual concepts or charts.
