Copywriting for accountant website in Australia

I need articles under each heading of my website www.benjenkin.com.au. In design this site is based on a similar site [login to view URL] and I would like similar content to this one but re-written at least eneough to satisfy copyscape. Also my firm is smaller and different so I would need someone who can correspond with me if neccessary via email or Google Talk about the articles. I use Joomla so headings can be changed or added if required. I was planning on doing the content myself but I have run out of time and inclination. For SEO purposes I wish to target people who are searching for an accountant, tax adviser or auditor in the Port Augusta region or they may be seeking general business information. I need a writer who is very proficient in English and is able to show they can grasp complex topics such as tax and superanuation in Australia. I need a writer who can come up with suggestions and who can demonstrate a good track record. In the future I will require a writer to change the content regularly and create a regular newsletter but that will be a separate job on GAF. Please treat this as a stand-alone project.
