The OP like many are surprised why they can't get genuine native, educated English writers with these sorts of announcements. The answer is simple: $5 per 300 words is a joke for those of us living in 1st world countries. Going rate for me personally is $50 per 500 words, but I know you can get good English writers cheaper at around $20/500 words. But $5? The only natives you'll find are those in high school.
We are not targeting only 1st world country peoples.
we dont have enough funds to spend 20$ per article.
5$ per 300 words is not bad for people who want to learn and improve his/her skills.
Thanks
