I noticed that most people here write for $15+, add this person on skype: eArticleWriter http://earticlewriter.com/ they do 500 words for $5 if you order bulk or $7.5, and while its not magazine quality, its definitely really good for the price and they do a decent amount of research, but probs not the best for bitcoin articles, but you can have try, but i doubt you can get article written for $2 for 500 words, i think minimum for a decent article is $1 per 100 words. You can check out warriorforum or bhw, for lots of different writers at good rates.
