It is vital that any individual applying must be qualified in this industry as the articles will be read by I.T professionals and therefore content must be written by qualified people with very good English grammar. I am seeking a long term-partnership as I need a constant delivery of articles, however as a test run, kindly write an article of approximately 400-600 words on the following topic: "Version control, an in-depth look at its purpose" If you have already written any articles related to what I need, then you do not have to conduct the test but I will need at least 5 sample articles. I will only pay for this article of good enough quality to publish. thank you, J
