Article Writing for my website. - repost

(Sorry guyz, this is a repost to the previous post as my manager had by mistake added a huge amount to be given to the freelancer and also he had quoted for very much articles in quantity to be written but my budget is very less than what was written in previous post. and I also need only 20 articles but within a week), I am still paying you a very big amount i.e. 12 dollars per hour and i am paying you for 60 hours but still freelancers bidding for less amount will be given preference. Write articles for my educational website, actually i am founder of this company or you can say organization and I also had got this website built even on freelancer.com but now I need some SEO articles to be written for this website. I need experienced persons and I will give more preference to bidders demanding less money and also will give more preference to bidders who had previously worked with me. But new freelancers can also bid, this is your time to show your talent. I am giving you lot of money, I am founder so I can give you a big bonus also if I like your work. Don't forget to send me some samples of your previously written articles and I will also give you any topic with keywords and you will have to write articles on that particular topic. Remember that i need 20 articles written in 7 days (I will give more preference to one who will commit for lesser time) or you can also give me your previously written articles. This is a very tough job, So, bid only when you are sure that you can complete this job on time and can do this job perfectly.
