Article Writers Required - Urgent

I require 30 articles to be written. Writer would need to research on the topic and write an article of 500 words. It needs to pass copyscape. There are some rules which I would like to clarify on the onset a) I can provide only 1$ per article. So writers who charge more than 1$ per article, please refrain from bidding here. You will not be selected. b) I will hold all the rights related to the article c) The article needs to be unique and pass copyscape d) Keyword if given needs to be present in the article e) Article length of 500 words f) Writer should be available on chat messenger ( preferably google talk or yahoo ) g) I require minimum 10 articles per day. g) And ofcourse the content grammar needs to be perfect. The writer thus selected would get regular projects from me.
