Essayedge is the great proofreader. I have been helped by essayedge - so many times. It is difficult to find a reliable proofreader in Japan. He always reads through my work in depth, and his corrections and suggestions are very accurate. Moreover, the service is fairly priced, and we can receive his proofread quite quickly. Publishing in English is getting more and more essential in my country. I do recommend Full Proof. I will use his support again.
Thank you for your kind words!
