American English Editing

I write regularly content on several blogs and I am not a native English speaking. I need a native American English editor who regularly proofreads and edits my articles. You should be a native American English person with a certain level of academic training and be ready to interact over skype and email with me regularly. You should be able to use Windows Live Writer (free program) and be able to post by that on my blogs after receiving editor rights the articles after editing. Your only task for every article is basically making sure that the American English is perfect. This is a continuous job: I pay for every article 5 USD. I write at least 2-3 articles a week.
