Copywriter required for website/offline marketing material

My current website is being overhauled and I need content either updated or completely re-written for approximately 20 pages. I'm also looking for someone who can update a blog possibly once every couple of weeks and write articles for our social media channels. Along with the website we are looking to update all our offline marketing and produce a company brochure. The site is being built as I'm posting so would require someone who could fit us in almost immediately.
