science fiction book cover

I'm looking for a skilled freelancer to design a book cover for an upcoming science fiction novel that I am writing. I need a design that will help convey the adventurous and exciting nature of the book, and capture the attention of the adult target audience. I have specific elements in mind that I want included on the cover, so I'm looking for a designer who can help me bring these ideas to life. The overall tone for the cover should be cosmic and mysterious, with an emphasis on the man character's weathered face. Trying to evoke a sort of Heavy Metal Magazine feel. If you believe you are the perfect freelancer for this job, please let me know.
