Chapter title art

I am writing a science fiction novel and am looking for an artist to create full page art to accompany new chapters. There will be 20-40 chapters. The art should be black and white but may include color if you are so inclined. I would like one artist to maintain a stylistic continuity. The novel will take 1-2 years to complete so please do not submit if not interested in the long haul. An artist credit will be included on the title page of the novel.
