I frequently get asked who I use for editing, who does my cover art etc, etc. So, I'd like to honor those people who help me make my books happen and give other authors a resource for thoroughly-vetted, professional artists and experts to help them in their own journeys to publication. If you want to succeed as an indie author, you can't scrimp on these things. Editing, cover art, and formatting are all critically important to success. So say we all.
For developmental and line editing I primarily use: Jeff Seymour. Jeff also does proofreading.
I'm also very comfortable recommending Richard Shealy for copy editing.
If you previously saw another editor listed here before, please know that I no longer recommend that editor. Not because I've had any negative experiences personally, but because I have had direct contact with individuals with whom that editor has been less than professional.
Many apologies to anyone who took my word as a an endorsement. I based my past recommendations on personal experience and on the experience of other authors I trust. All of that was nixed when I heard personally from someone with a significantly unprofessional contract with that editor. Again, apologies. Unfortunately, people can be unpredictable.
Galen Dara created the gorgeous header you see at the top of this page and she is doing a cover for me soon. Julie Dillon is the cover artist for the Dark Beyond the Stars anthology I'm a part of (and I hope to contract with her soon for more work).
I like to use either Vellum (an app for Mac which is insanely easy to use)
