I am looking for an English native speaker for a long term article writing service. Each week I need two UNIQUE articles, one is the news summary, development of this week on a certain topic; the other one is to review a book on a topic (You don't have to read it, you may search other people's review and rewrite it, or build up your own review after reading the content list, abstract, etc). Each article should be 200 ~ 500 words lengthy. Must be from English speaking country such as US, Canada, UK, Australia, and you must have experience in article writing (ideally with itrader>10). I will give you a broad topic and you come back to me each week two articles about that topic. The topic is finance / trading related, so it would be great if you are familiar with it. Please PM me your quote with sample, thanks. (again, do not do so if you are not an English native speaker).
