Content Writing

I am about to launch a business which provides mobile app development. We have been doing the business for a while but now want to start marketing it online and have developed a new draft website ([login to view URL]). The job is for someone to write/re-write the content for this new website and advise changes to web design to achieve a high conversion. Some of the high-level contents has been created but I need someone to add more detailed contents. We are promoting ourselves as 'Fast', 'Flawless', 'Affordable' - so these will need to be expanded. I will be able to supply key bullet points for each topic the write need to expand on (e.g about us, our team etc) but the writer would need to be creative and 'market' our business online. We will be looking at doing some online marketing like adwords so the contents need to convincing and achieve high conversion rate for visitors visiting our site. If required, we can change the website design or navigation to achieve better conversion. So, the primary goal is to get the website ready to go live & market online with good convincing content and design that converts. Note that we have skills for the design/development changes but need to be told what the changes should be and of course be supplied with the the copy write.
