Article Writing Project

I am looking for an article writer who can write articles on various topics. The articles need to be informative and should be written by native English speakers. They should be 100% error free, and should be spell checked. They should also be 100% unique, and should pass Copyscape. I will also be checking them using a custom plagiarism checking software. I need 15 - 25 articles written every week. The writer should provide the articles in time, and I will prefer writers who can deliver the articles quickly. I am willing to pay between $1-$2/article, and I am open to negotiations. I will choose writers based on their bidding price and quality. Remember that this is just a test project, and if I like your price, delivery time and work, I will increase the articles per week to around 50. Please provde samples along with your bids, and let me know your price per article via PMB.
