Add content to html pages on PHP website

We have a PHP website which is just launched. The website is just launched. We are looking for someone to smarten up the pages by adding content (not copywriting) to the HTML pages within the website via the adminzone. We think we need someone with PHP experience to be able to add the content as the pages are connected to each other. There is a strong possibility of additional work (applying development scripts, etc) as the website develops and to increasingly embellish member usability. The website is www.toptradespeople.co.uk or www.toptradespeople.com. This is an urgent project as we are looking to begin the SEO for this project imminently and want the basic pages to look well designed.
