I specialise in Proof-reading and editing essays of any sort of subject and can do this in approx. 3 hours depending on the length of the document. I prefer to utilise google documents as the individual can track the suggested editing and choose to accept/reject changes made. However, other forms of receiving feedback can be discussed. I can provide feedback post-reviewing an essay (if necessary) via skype as well as prior to editing should the person want to discuss how much editing/preferred form of editing needs to be described.
