You DO need a professional proofreader

Many realize they need editing for what they’ve written. Let’s face it, once you’ve read it countless times yourself, it’s more and more likely you’ll miss something. The best process is to have a professional edit for you, then have a proofreader insure everything is grammatically correct and punctuated sensibly and professionally. Both these efforts save YOU time and headaches, and most of all, prevent you from publishing mistakes. Looking polished can really make the difference between getting your points across clearly and supporting you reputation and mission versus coming across haphazard or unfinished. Not cool.

Take that smart step and seek an editor and/or proofreader while you do what you do well.
