100 Articles needed ( 500 words each )

Hi, We need 100 articles for various niche/topics. The word limit of each article is around 500 words. The articles must be fresh and unique ( must pass copyscape ). We will have complete rights once they will be delivered to us. Important: 1. You must know proper use of keyword density/prominence. (If you dont know about it then dont apply ) 2. Need at least 4 articles delivered per day. (If you cant deliver then dont apply ) Good quality alongwith cheap bid will be the winner! Provide at least one example of your work by PM. Once this project is done successfully another project is there for more articles. Please contact by PM for more details. Thanks.
