How much should one pay for someone to edit?

Hi all, I am a graduate student seeking a proof reader/editor to edit my papers (grammar and language structure).





I understand that professional editor usually request $50, even $80 dollars an hour (am I wrong about this?) But I'd like to hear from people what their opinions are on a reasonable pay rate for someone to look at 5 pages or 20 pages paper. How much should a client pay?
