I've seen freelancers list such services on Fiverr. It's nothing surprising. If a freelancer can put it in as a service, another website can offer it as a job for freelancers who can do it to accept and work on it. I've written 2,000 words articles for an amount close to it.Well, certain kind of freelancing jobs could be too good to be true. Having said that, I have seen many websites offering up to $300 per article. The fact of the matter remains that they (freelancers) also require technical expertise in order to make sure that they are qualified enough for the job.
