Ongoing article writing job(USD 2.5)

Need a good writer for ongoing unique well researched article writing jobs. Would like to start asap. This should be clear to those who have already done this kind of work before. Various topics. At first I may give you few articles to start off and then evaluate your articles. If i get what i expect then i will go ahead with the rest. My offer: USD 2.5 for a 600 word article. I thought this wouldn't be necessary for seasoned writers but decided to include for legality purposes anyway. In short: - Article rights will belong to me - Copyscape and DupeFree pass ( these tools are not perfect though i have my other ways to spot duplicate content so pls save us both time) - Humanly tone is a MUST and article has to have a personal touch(very important). - 100% original and unique while retaining the keywords (the keywords and their density will be provided to you in my separate email) - Prefer native speakers especially those from US and UK - Articles to be in Word and saved separately for easy cross referencing - Articles will be rejected or asked to be rewritten again if found unsatisfactory - Delivery of 30 articles within a week.(i'm flexible willing to give more time if you put in extra effort. jobs done in a hurry will be asked to review again) P.S: On thing i'd like to make clear. If you're busy to reply, keep me posted, tied up and not confident to deliver pls don't bid it's unfair to keep me hanging as well as your current employer.
