As a freelance writer, you are being paid to provide the best possible work you can. While you may have excellent spelling and grammatical skills, proofreading your work could be the difference between getting paid and having the content revoked. Never submit work to a client without proofreading it at least once. Otherwise, they may not be a client much longer.
