Really great advice. I just wish editors and proofreaders were more affordable. I find that the cost often dissuades writers from hiring help, even though it’s a really important investment. I like PaperBlazer (https://www.paperblazer.com/hire-a-proofreader-or-editor-for-your-novel/) since it’s more affordable than a lot of other editors. The other comments here are very helpful as well.
In return for the sacrifices you must make in order to self-publish, you will gain total control over the project. In addition, any profits from sales of the book will be yours (not just a royalty percentage as with either a traditional publisher or a vanity press), and in some cases it may be the only way of getting your book into the hands of readers. However, there is no getting around the requirement to get the tasks done one way or another.
Check out freelance websites like UpWorkor even a great site called Scribendi. (Warning: if you source an editor from these sites, make sure you hire another, professional editor to go over it afterward. There is no way to know what you are getting otherwise. Just because the draft comes back better than it was before, does not mean it was well-edited!)
As one person who “woke up and decided since I’m published and an English major, I should be an editor,” I can see your point of being only one type of editor. I’m not a good copyeditor at all and don’t offer my services for that situation. It’s funny that you would say a traditionally published type editor would be better than the independently published editor. I found this to be totally untrue since I have worked with both. My traditional editors from St. Martins Press and Bantam books working a total of 35 years in the industry, was the worst editor of all. My independently published editor/book coach, is the most knowledgeable. So there is a bit of a disparage. It’s not an absolute science, editing.
Software and Systems – Some of us writers like using certain types of writing tools or software. I personally love to write my books using Scrivener, and will then switch to Google docs for better tracking systems. However, I've run into editors who only use Word document. That's no bueno for me. So, make sure they are good with whatever writing programs you want to use.
2. Copyeditors aren’t the last line of defense when it comes to a book’s mistakes. Formatting, which is done after an editor has done their job, can lead to unintended errors being introduced into the text. That’s why it’s important to hire proofreaders to comb through edited text *after* the book has been formatted for print or digital. Proofreaders are your last line of defense—but they’re human too.
