Hi Sean, as an editor I run permissions for authors. It’s a case of contacting each right-owner (author or publisher) where the quotes are not deemed public domain, and provide them with context for approval. You can do this yourself or I’d be happy to quote for the work, if you’d like to contact me directly? My email address is firstname.lastname@example.org.
Freelance editors normally do not double as literary agents. Not only is it not our area of expertise, but it can actually lead to ethical quandaries. There have, unfortunately, been cases of literary agents saying that potential clients’ work “has potential” but needs to be edited (by them or their employee), for an exorbidant fee. It would also be possible for editors to give the impression that they are guaranteeing publication of a project, when that is something no one but a publisher can do. Many professional organizations forbid their members to combine these two roles, to avoid a possible conflict of interest.
The greatest benefit of an editor is that he or she is not the author. An editor is someone else. Some editors are professional writers, but every single one of them is a professional reader. As a writer, you’re probably a voracious reader, but you can never be a true reader for your book. By bringing forth a book into the world, you’re asking other people to read something you’ve never read. If you sincerely want the book to be the very best that it can be, then you must ask someone else to read it first. You owe it to your book, to yourself, and to your readers.
If you know you are sensitive to changes, or that you only want edits that correct what’s wrong (and not subjective edits beyond that), tell the editor so. This kind of information is invaluable, and will prevent frustrations and misunderstandings. That said, don’t suggest this if you’re open to your work being better. Editors will bring your work to a whole other level if you’re able to loosen your grip on any notion that your creative expression is under attack when an editor makes changes to your work. The most successful authors are edited multiple times over.
In fact, Pressfield writes, “Resistance is experienced as fear; the degree of fear equates to the strength of Resistance. Therefore the more fear we feel about a specific enterprise, the more certain we can be that that enterprise is important to us and to the growth of our soul. That’s why we feel so much Resistance. If it meant nothing to us, there’d be no Resistance.”
