need an image set constructed

I'm looking for someone who has time to construct a very specific set of images with different lighting (in a graphics program of some sort). If you have used blender before, I know it would work, but there are lots of image/graphics programs that would also work. It has to be something that allows you to tweak the position of the light and shadows (simulating the earth's rotation).

If anyone is interested, give me a shout. I believe I can find some funding for this effort.
