Detailing PowerPoint slides

I need a freelancer to help me develop a PowerPoint presentation for training purposes. This presentation consists of 100-200 slides and I require in-depth content development for each slide. The freelancer must have experience crafting PowerPoint presentations for training purposes that clearly convey the message I am trying to send. The slides should be well thought-out, visually appealing, and engaging. Experience with financial language and concepts would be an advantage. The freelancer must have excellent communication skills and be able to collaborate with me to create a top-notch presentation that is sure to capture my audience's attention.
