This is always an option. However, the “quality” designers will charge you anywhere from $30-$97 and that will be for just one ecover.
For example:



The cheaper sites will also provide only one ecover and most likely will be just changing the text on pre-made templates.
Plus, if you want the .psd files to make edits, you will need photoshop and will also have to pay extra. The same goes with getting 2D images of your covers.
Wouldn’t you rather create unlimited 3D and 2D ecovers that are 100% original and yours to edit and revise? We think so!
