Additionally, I think that many GREAT, very reputable editors absolutely will not complete a sample edit for free. They can point you to their work, their testimonials, and their references, though, free of charge. And if you’re curious why editors I know do not offer a free sample edit, check out this video to illustrate the point. https://youtu.be/essNmNOrQto
I usually ask for a 10-20 page sample – one page is a bit scant for a really accurate estimate. I’ll do an editing sample, too, but how long I’m willing to make it depends on the proposed length of the piece I’ll be editing. As for the “hidden message” strategy, if I saw something like that, I’d suspect the prospective client was fearful and suspicious and I’d probably run the other way. I willingly provide testimonials, references, and links to published work, so tricks aren’t necessary. It’s important to me to build a professional relationship of mutual trust with my clients, backed up, of course, by a contract that protects us both. I don’t think I’d like to work with a client who plays “gotcha!” Lots of good suggestions in this article, though.
So because of this and because I don’t live in NYC or LA, I decided I may have better luck writing a book, which I have been doing for several months now and enjoy; however, I know it needs work and I can’t go back to the 5th grade and pay better attention to the simple “put your period here and comma there” lessons so I was hoping to learn as I go with reading, writing and seeing my finished product after hiring an editor.
