Article Writing

I require a someone to write 30 original articles for me. I will supply you with 30 keywords around one niche topic that will form the basis of the articles. One article needs to 1500 words in length (my main keyword must appear at least 15 times in this article). The other 29 articles must be a minimum of 1000 words in length (the main keyword for each of these articles must feature at least 10 times in the article relating to that particular keyword). So to reiterate, you must write: 1 x 1500 word article (around one keyword I will supply). 29 X 1000 word articles. (around 29 keywords I will supply) I am paying a set rate of $100 for ALL of the articles (around $3 per article). That is the maximum I'm paying so if it's not enough please don't bid. If you bid over $100 you wont be considered either so don't waste your own or my time. All of the articles must be researched and original. I will be checking for plagiarism and if you have lifted the content from an already published article you will have to start again. I repeat, I want original content for these articles. I will set up a milestone of $50 to get you started but this will only be released once I have approved the first 15 articles. The outstanding $50 will be paid when you have completed all of the articles and I have approved them. As I need well-written articles, I am looking for a writer who is very good with English. You will have a better chance of winning the project if you attach a sample of your writing with your bid. I require you to send me the articles as you finish them so that I can check the copy and approve or reject it. You will have a maximum of one month to complete all of the articles. Thank you.
