presentation

I am in need of a presentation to be created with the PowerPoint software. I already have a template ready to use and will not require assistance with the design. The overall presentation should be more than 20 minutes. I am looking for someone who is creative and can come up with engaging ideas that can be expressed in a visual presentation. I also need someone who can work with me to help refine the presentation materials for any clarification that is needed. This job requires a great understanding of color palettes, typography, graphics and creating a user experience. The graphics, text style and content should be constructed in a professional manner and quality. I am looking for someone who has strong attention to detail and is willing to provide revisions if necessary, until I am satisfied with the end product.
