Power Point Presentation Writing

I am creating a 10 to 15 slide Power Point Presentation. The presentation will be for a client that will be renewing their service contract. I would like to present my company and our company experience, our new service management software and how it allows us to efficiently manage their stores, and how we are increasingly taking steps to become a green environmentally friendly company. I need someone to write the text for each slide. The presentation will be a 5 minute presentation. Each slide will not have very much text, just some key bullet points on some, and some short to the point text on the others. I need it to sound professional.
