looking for researcher/article writer

I'm looking for someone to write short, 250-word, very general articles on a variety of topics.
They will need to be unique and, most importantly, they will need to be accurately researched with sources of information cited.
If I find someone reliable for this, I hope to scale this project up to where I'll eventually be sending them as many as 20 articles a day.
If you're interested, please PM me with your rate, experience and where I can find samples of your work and I'll get back to you with more details.
