It all depends on the project and how much work is needed. Normally $0.30c/0.23 Euro per word. It depends on the type of document you want proofread. I charge a minimum of 10 Euro which covers the first 2000 words of any document. After this threshhold, my basic fee is 5.40 Euro for each additional 1000 words. If your document exceeds 10,000 words, I offer a 10% discount.
