Creating PowerPoint presentation

I require assistance in developing an engaging and informative PowerPoint presentation. The presentation should clearly convey key information relating to my company's products in a visually appealing manner. It must incorporate high-quality graphics, animations and transitions to help the audience effortlessly follow the content. Appropriate use of headings, sub-headings and colour coding is important to structure the presentation in a logical flow. PowerPoint will include 20+ slides and cover 4 main product areas. Basic content information will be provided.
In addition to that, our main product overview document (MS Word) will need to be updated to give it a more professional look and feel.
