Looking for quality rewriters to rewrite 10 articles daily. The total project is 50 rewritten articles. I will supply all keywords for the articles and any other details for the articles. Looking for 5 to 6 good writers. Pay is $1.00 to start per 500-600 word article and will increase it with proven reliability and writing skills. I pay at the completion of each 50 article project with $10 sent after the first set of 10 articles are received for new writers and the remaining $40 sent within 24 hours of receiving the remaining 40 articles. Native English writers preferred with a natural writing style. Must pass plagiarism checkers 100%. Need keyword used in first sentence and 1-2 times per paragraph for a total of 2-3% keyword density. Grammatically correct, spell checked, broken into paragraphs, and have great tone and flow. Adding personality to the articles is allowed and suggested. If there are too many grammar, punctuation or spelling errors, etc I will have to send them back to you for reworking before sending off the next batch. Please be able to communicate at least once per day. Before bids are considered a 200-300 word rewritten sample is needed to test quality. Looking to fill slots ASAP. Thanks!
