You probably already know how important a good cover is. Save your pennies for a graphic designer who has experience and knows what he’s doing. And don’t forget to have them create a back cover and a spine, whether or not you’re planning a paperback release. You might want one at some point.
Covers are one thing; but interior design is also important. A novel, even an ebook, can and should have a flow and design. It should be graceful, easy on the eyes, and consistent from chapter to chapter. Joel Friedlander has some wonderful interior book design templates for print that are very affordable. And if you’re doing several books, consider PressBooks. They’ll give you BOTH a print and ebook version.
