Factual Web Copy, Article Research, creation and submission

We are developing a number of web sites and need some work doing on the following areas:
1) Factual writing, proof reading and general \"knocking into shape\" for the about us, privacy, how to buy etc etc sections.
2) Research and create article / blog and site content relevant to to the products we sell.
Full specs and keyword guidance will be given.
Regular ongoing requirement - we have a number of projects either in research or build phase as we speak.
Your written english must be gramatically correct, literal and geared for the UK market ( colour has a \"u\" in it the UK :)).
You must be confident and concise, creative and proactive. Within reason , I am happy to let you \"work up\" all the areas as long as they are relevant to the products we are selling.
A famiiarity with the concepts of SEO would be an advantage.
