we employ both ENL (English as a native language)
Your native writers either suck or leave after a few months. That's what happens when you pay $6/page.
If the native speaking writer is currently not available for completing a paper in any particular specialization, the paper can be completed by a non-native speaking writer, whose knowledge of English still corresponds to the highest TOEFL level mark.
So, if the customer asks and pays for a native writer, they might still get an ESL writer. So you do lie. And overcharge while underpaying. Thanks for clearing that up.
