power point support story telling

I am looking for someone to help create a PowerPoint presentation with the purpose of persuading an audience about a product or service I am promoting. The design of the presentation should reflect a corporate style and be professional in appearance; however, it should also be creative and engaging to ensure that the audience is engaged. My goal in creating this presentation is to ensure that my message is conveyed effectively while using attractive visuals and concise text to effectively captivate and persuade my audience.
