Create illustrations for a movie project

I am planning to make a low budget film. I need to raise funds to make the film. So I need to 'pitch' it to people. I need some illustrations to assist in telling the story. I will require 25 high-quality illustrations. These can be delivered as high-resolution jpegs - approx A4 landscape. I will load each image as a page into a Powerpoint presentation so that I can talk through the plot. The illustrations can be colour or black and white, but probably black-and-white would suit the story better. This is the story of a rich psychopath who lives in a luxury penthouse. It is a dark and disturbing story, which requires a style that is more illustrative than 'cartoon-like'. I will supply the rough 'stick-man' guides for each frame of the storyboard, along with a description of what we should be seeing. If the illustrator has questions, I will be very quick to respond. These need to be slightly more detailed than normal storyboards. They should obviously give a sense of the quality and detail of the production. Deadline is tight. Must all be completed by July 14th. Please submit a sample of your illustration work - bearing in mind that we're looking for a slick, professional, but dark and even disturbing style. Thank you.
