Power point presentation -- 2

I am looking for someone experienced with PowerPoint presentations for investment banking to create one with a specific purpose. The goal of the presentation should be to inform viewers, and I would like it to contain 10-20 slides. I have specific guidelines and design requirements that must be followed; this means taking my ideas and creating a presentation that is professionally designed and aesthetically pleasing. Additionally, the presentation must be created in an efficient and timely manner. Any relevant experience or qualifications you have should be highlighted, as I am looking for a designer who is both reliable and qualified.
