Looking for a writing expert with competence in American education

I’m looking for a writing expert who is well-versed in American education specifically related to Math. I would like the person to revise and edit three blog posts for me with a total of 350 words. The posts must be accurate and well-researched in order to deliver quality content to the reader. Above all else, the most important thing is to make sure that the writing is grammatically correct and has no issues with easibility.
