Editing/Proofreading/SEO Web site text

We have eleven Word documents totaling 3100 words of Web site text that need to be edited/proofread. Bidders must be native English - preferably GB English - speakers and have an excellent command of written English. Work must be free of typos and grammatical errors. SEO and keyword optimization are important to us. We are ultimately looking to establish an ongoing relationship with a copywriter who will prepare regular news items and suchlike for our site. Payment will be made over PayPal per 1000 words after they have been accepted by us.
