Three images to post on web of book cover

This is for a book cover for a new book that I am hoping to write. I need some help with creating a book cover design. I need three images: (1) the actual image for the book cover design (same size as [login to view URL]), (2) smaller version (~ 600 pixel width), (3) very small version (size of attached [login to view URL]). The title of the book is: The Brilliant Path: Creating a Purpose-Filled Life I was thinking that there could be two colors on the book cover (like the image of the attached peoplework book cover, which is blue and white). I was thinking that the top half of the book cover should be blue, and blend in with the image below of the path through the field. I would like the bottom half of book to be either orange or yellow (to match the color of the plants in the field in the image). I would like my name at the bottom of the book cover image (which I will give to the winning bidder).
