book cover

I need a book cover done. I've drawn my own but it doesn't look very "buyable" if you know what I mean. I also have some sketches done of what I want it to look like. I am young, I can't offer too much. I don't exactly need it right now either, but I need to know what I can get for what I have. Now, mind you, the book might not sell very well, but if you do well, I have no problem getting you tons of free advertising and potential future jobs. I wanted the cover to have a male's face in the background, profile view, mostly just his mouth/ chin and neck while the rest of the bottom of the cover is a sort of greenish blue forest with a woman in rags walking through and looking up at the sky, her back to the audience. The male is an elf and the female is human. It's a fantasy romance book.
