I have used many copy-editing, proofreading companies so far. TypeRight was the WORST... When I complaint, the manager said he/she didn't understand my frustration, saying that they"ONLY proofread documents that have ALREADY been professionally edited". Why would I need copy-editing, if a document has been professionally edited? The manager also said" proofread will catch ONE or TWO errors per page." Haha... There are many other copy-editing, proofreading companies to try. I would NOT use TypeRight.
