Looking for a talented content editor for long term work!

I am looking for a content editor to help facilitate our content production. I run a number of sites that we are regularly producing content for. Were looking for someone who will take the blog content from our excellent content writers and do the following: - edit the content to improve the value to readers. This includes finding sources and citations and referring to other websites where appropriate. - editing the content to improve wording - adding relevant internal links to other pages on the site. - optimising the content from an SEO perspective. - writing optimised meta titles and descriptions.
