250 words Articles needed for 0.5$ per article

Hi I need 23 articles 250 words each on three different topics. The topics are really easy to understand. But i want all the 23*3=69 articles by 28th jan, 2010. I'll pay 0.5$ per article. You can also chose even any one topic but i need 23 articles on that topic within the time given. The topics are as follows - 1. Link Popularity 2. Link Building 3. Link Directory *** The articles must be 100% copyscape passed and making sense. Any use of fluffing words will cause the nonacceptance of the article. so plz make sure this thing before.
