Copywriting for a website

I am looking for a copy writer to put together our website content. I work for a new company called iPro and we are about to launch a isotonic drink (a bit like Lucozade, but better!).

Our flavours are Orange & Pineapple, Citrus Blend and Berry Mix. the website pages are: about us/why drink iPro/the products/our history etc. we need somebody who can write in a professional but fun way as this has a quite a modern vibe but should be taken seriously.

The website is being created right now so there is a real rush on getting the copy this week.
