Extra notes: I've done a PowerPoint Mock-up of how I hope the book covers (back, front and spine) might look. But since I'm only using Windows Paint to edit my images, it's pretty Low-Res... And I need a professional opinion. Also, I'd like to add some colour but am at a loss as to how to do this with Paint. This job should not take too long though. The design is pretty simple and I've provided as much detail as possible about what I want. There is a higher-res eps file for the images available but it is too big to upload here.
