I'm very new to freelancing, so my rates are low! I don't look great on paper since I have no formal training, but give me a shot; I have a verbal IQ of 145, I've been editing casually for years, and I've recently found grammatical or punctuation errors in displays at the Library of Congress and the Smithsonian Museum of Natural History, as well as on the SpaceX website.
Ideally, I'd like to build a long term relationship with someone who needs editing on a regular basis. I'm free during the day, so I could potentially edit emails, etc. on very short notice. I'm friendly to ESL speakers and people with disabilities, and I'll never be judgemental.
