Creative writing required as website content for a service provider

I am looking for a writer to help produce? new content for our website to promote our business and products. We are a ISP/Hosting provider (Hosted Exchange, VoIP, Internet etc) based in Australia and have an existing set of content that sorely needs improvement. I am more then happy to spend time explaining our products to you but I am also looking for someone who can do more then just reword my own explanations. The end result should be concise and easy for potential customers to understand. My business is not an "Enterprise provider" in the American sense of the word, we're also looking for our content to be a bit light hearted and not contain overbearing tones of *corporateness*. Initial content articles to be written/improved. * Hosted Exchange Product Overview * Hosted Exchange Technical Explanation * VoIP PBX Product Overview * Company History * IP WAN Service Overview * Why choose us? * Infrastructure as a Service Product Overview
