Hi....
I met all your requirements (serious, cs passed high quality articles, 100% completion with in the stipulated time, long term) and I am the one you are looking for....
I have vast experience in article writing and I can easily write 500 word articles on all major niches...
Just msg me once so that I can attach some of my sample articles (As per this website's rules, I can't attach my samples until you start conversation with me through freelancer.com).......
You can even assign me some keywords and after getting satisfied with my articles only assign me the project....
Moreover I am an Indian, so 24*7 mobile contact possible. Eagerly waiting for your positive reply......
