10 Scene concept sketches needed

I am looking for an artist to create roughly 10 (possibly more) black & white (or possibly color depending on price) sketches that describe a few different scenes of a story I am writing. The story is rated "R" and contains adult situations that deal with sex, the devil, God and nightmares. I would like them to have a serious "WOW" factor to them so they may need to be fairly detailed.

There are charactors that have already been created and are to be used as "base of design" or reference when using them in the certain scenes.I have included some samples of them in this ad. I am not sure of the size but something like 16.9 ratio.

These will be used on a website and I want the originals mailed to me as well as scanned and emailed.

I have listed a fixed price total of 250. 00 to give an idea of my budget because it is required to post the ad - perhaps and hourly rate would be more cost effective?

Also a quick turn around is needed for this.

PLEASE NOTE: These drawings do not have to be hand drawn sketch's - if there is a software program out there that can do what I am looking for - I will accept if they have the visual "power" I am needing.
