Background
I am a native English speaker with 3 degrees, who just retired from a very successful 30-year career in teaching. I used to teach powerpoint to my students so that they could present their research findings.
Relevant experience
As a teacher, I have designed many different types of communication: newsletters, blogs, reports, websites, proposals and speeches for conferences. Sometimes clients prefer a very plain presentation style. At other times they would like something more creative.
The Slideshow
The layout of the slideshow should reflect the professionalism of your endeavor. At times humor may keep the audience interested. At other times, it is inappropriate. The information needs to be presented in perfect English with quality explanations to entice your clients to engage in your services.
Animations need to be used sparingly so that they don't overwhelm the message. In a similar manner, graphics should always enhance the message. If the slideshow uses figures, graphs are a dramatic way to display the pertinent information.
I will strive to determine your needs so that I can deliver what you want.
Work Ethic
I will work diligently and complete the slideshow in perfect English.
