Copywriter required

I require a talented and experienced writer to produce final copy for a number of websites and brochures. I'll be able to provide you with the required information and roughly "what I want the text to say", but it's up to you to make it significantly better.

Initially this is for a number of websites, but may later include blog entries and tweets. Further work is most definitely a possibility.

A perfect grasp of grammar, British English spelling/grammar weirdness and the ability to comprehend a sometimes slightly vague requirement is a huge bonus.
