After researching a lot of different designers, I went with Ebook Launch for my debut novel because there wasn't a single cover in their portfolio I didn't like. I didn't know exactly what I wanted, but I knew what I liked and what I didn't like, and they took my mishmash of half-formed ideas and turned it into a beautiful, eye-catching, genre-appropriate design! Not only that, but they were speedy, responsive, and accessible. A real pleasure to work with. I will definitely be coming back to them for the rest of the covers in the series.
It’s always sensible to follow due diligence in submitting your first draft of your book to an editor by making as fool-proof a copy as possible for you because first, it is your own creation, and secondly, a horrid draft sent your editor can end up frustrating both you and him or her. Make your own corrections to the extent you can, so that will make the job of your editor that much lighter and the end result would be a lot more effective.
