Book illustration

I need five line drawing book illustrations of a couple in situations of ordinary life; must accept partial payment now, partial payment on spec (contingent on book sales). Alternatively, if I cannot find the right artist to create five drawings on this basis, I may commission one drawing only for the cover, to be paid in full upon completion. Controversial subject (involves reincarnation, life after death). I need two actual persons depicted and recognizable (images provided), but they can be in a semi-realistic, whimsical style.
