40 articles--$80

I need 40 articles in 4-5 days. All have to be completed perfectly. Daily submissions of 8-10 is MUST. All pages must be 100% Copyscape pass. All must be grammatically perfect. There are some instructions for the task which have to be followed perfectly and any neglect will result in revision of articles. My budget for these 40 articles is $70-$80. Payment via Freelancer/ NO escrow as we have lost money in paying writers who provide crap work and then get us in trouble by creating Disputes. You will be paid as soon as the articles are checked(within a day or so). We need multiple writers. So start bidding with samples. regards
