power point presentation

I am looking to create a power point presentation to help build my company's profile. I would like the presentation to have between 10 and 20 slides. It should be informative and persuasive in nature, and I will provide the necessary multimedia elements (such as images and videos) for inclusion in the presentation. I am looking for someone with experience in creating power point presentations, and who can help create something both visually presentable and effective when it comes to conveying the right information.
