Help set-up and manage our internet/database marketing needs

We are an early stage tech start-up based in Queensland Australia and require the help of an experienced internet/database marketing expert. We require help to both set-up and manage, on an ongoing basis, all our internet/database marketing needs, which are primarily based around customer acquisition. We are looking for someone to take control and make it happen. You will be required to work with little supervision and the role comes with a great deal of flexibility around days/hours worked. Only people based in Australia will be considered, but not necessarily Queensland. Ideally the person would have writing skills to help craft the content/material, but this can be outsourced if required.
