Freelancers are not reliable, no matter how much they try to convince others of their legitimacy. I got my book draft proofread by a freelancer who took a great deal of money for the work, and when I submitted it to the publishing house, they rejected my manuscript on grammatical and formatting errors basis. When I tried to get in touch with that freelancer again, they were not available. I had to hire one of the most reliable proofreading services in UAE with more money. The proofreading company made the best effort and my draft was selected for publishing on the first try. The book proofreaders there were highly professional and experienced. These freelancers just waste our money and time.
