Blog/Knowledgebase article writer

We require an article writer who can provide articles based on a 'topic'. The topic will be provided each time, with a short introduction on anything that needs clarification. The topics will be centred about Internet and Email marketing and as such, the writer must be technical as well as literal. We may also provide a link to an existing item that would need to be re-written. The articles will be around 4-700 words each, depending on the subject. This will be ongoing work and could be worth a lot of money on a monthly basis as there are a large number of areas we would like information written on. Only writers who have experience in this area need apply. Rewrites MUST pass Copyscape and should have impeccable grammar and spellings. Initial project will be for 10 documents to allow a review of the quality and confirm other areas.
