Summarize my PhD dissertation into a PowerPoint presentation for defense.

I am in need of an experienced freelancer to summarize my PhD dissertation into a PowerPoint presentation for defense. My dissertation has a total word count of more than 20,000 words and focuses on industrial and organizational psychology research. I would like the PowerPoint presentation to be 40-45 slides long. The presentation should include an outline, summary of key points, as well as visual elements to engage the audience. The freelancer should have strong writing skills and experience creating a compelling and professional looking presentation both in content and design.
