Powerpoint Proofing

I'm looking for a freelancer to help me with proofing and enhancing the design of a PowerPoint presentation on Africa and the role of the underground to help its peoples and environment with clean water, sewerage, transportation and power. I am an excellent presenter - but I need help to make my presentations reflect the quality and seriousness of the topic. It is for an educational purpose to be delivered late this week in Africa - and contains nearly 100 slides. I believe that this project requires both proofreading and design expertise to ensure that the presentation is effective and well-polished. The PPT is finished - it needs polishing. If the first PPT goes well I will have immediately more related (common slides) powerpoints. I'm excited to work together with a talented freelancer and look forward to seeing the results!
