Articles Writer Needed For 20 Articles - English

Hi freelancers, I need a writer for a minimum of 20 articles. Here's the features I need: 1) English must be excellent without any kind of error. 2) You will have to manage to retrieve the content and the title for the articles. 3) Articles must be between 450 and 600 words (or a little more). 4) Articles must be original and have to pass 100% the copyscape. 5) I'll give you the keywords and you will write the articles with a keyword density of about 4-5%. 6) You must provide an image along with each article of exactly 630x250px (or 960x280px). 7) You must provide a description of about 160 chars for each article. 8) You must be willing to rewrite an article if is needed. 9) A certain number of articles (maybe 5) must be for EzineArticles. 10) If is needed, you have to highlight some keywords (simply changing the color). 11) Articles must be divided in paragraphs of maximum 6-7 rows. I'll check the articles before paying so, please, bid only if you're serious and only if you have already feedback and only if you can provide all the tasks above. Also, send me a sample of your past works, and the details of your bid. You must be available to communicate through email. I would like to pay a maximum of $2.50 for each article but lower bids are appreciated. Eventually, if things go well we can build a long-term partnership. Happy bidding to all.
