Grant, you’ve got a lot of info in here that I LOVE! I swear to god, if I read another blog post telling me about a side hustle and I read the word “fiverr” I’m going to implode. You bring up an AWESOME point about not trying to compete in market places where your only advantage is price; eventually you’re profit will be ground down to 0. I’ve heard of domain reselling before; there might be a course there for you… (I’d buy). Great post!
In addition to being a meticulous writer from a mechanical standpoint, you must be the kind of person who pays close attention to detail. Keep in mind, a proofreader is not the same as an editor. You’re not reviewing what your clients are trying to communicate, but rather how they write it in terms of spelling, punctuation, typographical errors, and word usage.
