Web Illustrations

I'm in need of a set of 17 line drawings for an underwear website (image 1). Each drawing is of a different style of underpants and shows how they fit the body (some of the bodies are children, some women, some men, and some pregnant women. Some of the styles are variations of the other styles). These are to be drawn either from a line drawing I have or from a photograph of the underwear. I'm looking for black lines, white backgrounds and I'd quite like the pants to be filled in with a pattern design I already have (this will probably have to be redrawn to look more professional) (image 2).

I also require 15 illustrations of those drawings in a file format where I can drop photographs of fabric into the main body part of the pants and drop fabric or fill with colour into the waist and leg bands (image 3).

The underwear is all made with bright and fun fabric so I'd like the drawing style to reflect that.
