Front / Back Cover for my book

I am looking for a creative designer to create the perfect front and back covers for my book. I need these covers to be printed most likely by Amazon on demand service, i will have hardback and softback options, and I am supplying all the images, but I am open to changes / other ideas. That being said, I'm not sure what type of finish I want so I'd be open to suggestions from the designer. I'm looking for a unique and eye-catching design that stands out from the crowd and will draw people to check out my book.
