English language copy-writer needed (ongoing - fixed price quoted is monthly)

I'm looking for someone who can provide one article per week on an ongoing basis on subjects associated to HR and Recruitment.

These could include careers, recruitment, interviewing, people development, leadership, team management etc. From time to time we may provide soundbites or data that can form the basis of an article but in general we would want the copy-writer to identify topics and draft the articles. We're a Mongolian Executive Search company and our website can be seen on www.MongoliaTalentNetwork.com. Sample articles can be found attached.
