Prepare powerpoint presentation

I need someone to help me create a persuasive powerpoint presentation with a corporate design for my business. The presentation should be made with up to 20-25 slides. Details are important and so special attention must be paid to the design of the slides. I'd also like this presentation to be professional and dynamic to capture audience attention. The information included in this presentation will be valuable and speak to the quality of my business. Please make sure that you have experience in creating presentations before - strong graphics, simple ways to effectively convey the message, and overall fluidity is key.
