I pay my writers an average of $2.75 per hour, for that I get several blog posts per hour following a particular preset method of layout, cropping/resizing of photos and scheduling.
If you use
oDesk for Writers you will find many writers with excellent English. All you need to do is make an account, register a credit card for which they take $10 deposit in two uneven transactions which you then report back to them to verify the card, then they refund the $10. From there write a really descriptive job description and within a few hours you will have up to 100 applications from great writers of the English language.
