Book cover and images

I am an author of a book I plan to self publish and need a cover design and images for the interior. Graphic design, not cartoons or corporate design Some freehand or illustration capabilities Manipulation of existing images such as public pictures available from the hubble telescope. Job Description: Collaborate to understand the underlying concept and turn that concept into an image Manipulate existing images in such as way as they become "wallpaper" for an image (the outline of a man with the interior being a wallpaper of galaxies) or overlaid onto each other (a picture of the earth overlaid onto a supernova) Open minded to spiritual or religous concepts (although you don't have to agree with them, but be comfortable with the topic as the images requested are pictorial representations of a spiritual subject) Ability to think outside the box and be creative Have an existing template agreement that assigns all rights to the images to my project Prefer to work with a fixed budget per image but open to hourly with a cap.
