Your calculation of price is incorrect, unless you've posted for just one article to be edited. As you've posted it, it appears to be 175,000 words. Divide that by 6000 words and you get $29.17, not two dollars, in which case your actual cost if you multiply that by 350 articles is $10209.50, a far cry from $30 or even $250. See PMB for your sample--your description itself needed editing--and further information.
