Researching, Fact Checking, Updating and Editing Case Studies and Articles

I have a number of old articles and case studies which require updating, fact checking and editing. I am looking to hire an AU based freelancer to help. The articles are all related to franchising in Australia. We are looking to use the updated material in both a refreshed website, online articles, newsletter content and a repository of assets. The challenge may also be to extract content from media articles we have published and stitch together stories and content from our executives into a cohesive whole. An example of that would be the article attached. We would want to expurgate the non-company executive content and only use our content. This is a relatively straight forward job for an Australian based business writer with native English. I want no fuss, get the job done type of person. For the right person with the right quality this is a relationship that will be ongoing.
