Illustrate Something

I need a series of illustrations to describe the musculoskeletal disorders or discomfort associated with long hours of computer use. The image has to first show full torso back and arms that sequentially highlights the neck, shoulders, upper, middle and lower back, and finally the wrists and hands. I then need to zoom into the forearm and hand, and sequentially highlight the different parts of the body being effected. These are the muscles, tendons, ligaments, nerves, vascular structures and finally the bone. I then need the figure to become a little cartoon person illustrating the development of an injury. • First – tingling in their fingers • Second – some weakness in the hand and aching • Finally – severe pain and loss of function in the hand. This short presentation should take about 1 minutes with a 10 second pause between drawings of the body and the illustration becoming a cartoon figure. I would like it to mostly be black and white with splashes of colour to highlight the key point of the illustration (e.g. pain in the neck) I am looking for clean lines, not too serious (but not childish) illustrations (see file attached for type of illustration I need). I am on a budget, but need a good quality product that can be run inside a PowerPoint presentation or the stills put into a handout. I am looking for an illustrator that I can call on in the future to illustrate other training tools, such as flash cards. Thanks Liz
