Here are some services EAs might use more if they had easier access:
- copyediting (in-depth editing of a piece to making it clearer, etc)
- proofreading (more nitty-gritty spelling and grammar checking)
- formatting into a specific format (markdown, etc)
Larger organizations usually hire or contract with at least one copyeditor and to help make their written work clearer and more consistent. But a lot of people might want occasional copyediting and not find it worthwhile to go through the hassle of finding someone to do it. Particularly if they want someone with enough knowledge of EA that they can help improve and clarify EA-specific material.
A colleague writes, "I've had ~10 people ask me in the last year about finding copyeditor services, and have recommended them to many more people. Would be great to have a bank of available people who authors could hire."
I would be excited if someone started a project coordinating this! Similar to what Pineapple Operations is doing with personal and executive assistants.
