Copy checker for website

We are developing a water filter website, aimed at a market of 20-40 yo, mainly urban, interested in sport and fitness, who buy Evian and Vittel water bottles.
Probably university educated, or at least A levels. Mainly female bias.

I have written 5 pages of copy, with pictures for a website.
Headings are: home, products, FAQ, technical and ordering

We want the website to be engaging, authoritative and accessible/user friendly.

We are looking for somebody who can hone the copy down to make an impact, get the message across and generate sales.
Please do let us know what you have worked on in the last 6 months,

Simon
