The book cover is the first thing the reader will see, so it HAS to be an attention grabber; think competition level!
If you just got a little queasy and started seeing dollar signs dancing in your head take a deep breath and relax. You don’t need to spend $400-$600 on a cover designer. There are affordable alternatives out there.
> Besides the affordable designers I have referred people to in the past you can also resort to methods like a Google search using a search term like ‘free ebook covers’ or check out odesk.com or fiverr.com . (Don’t be too quick to settle; look at sample of their work and ask for references.)
> Another option is to contact the local high-school or community college graphic design department and offer a promising student the opportunity to add to their portfolio in exchange for taking part in a literary endeavor.
