Caricatures of Cast Members on Film

We are looking for a good sketch artist to do a line drawing that would be used for our wrap t-shirts given out to the cast and crew at the end of our film. Back of shirt: A precarious mountain summit with a helicopter hovering over the top with a climber hanging off the helicopter. A line of climbers climbing up the side of a mountain, with a camera crew just under them, also on the side of the mountain filming the climbers. We want this to look precarious (like why would anyone want to do this??) but humorous (intended to make people laugh looking at it). Front of shirt: Where the pocket of a tshirt would typically be: a porto-potty with a harness hanging on the side and climbing boot crampons laying just outside like there is someone inside. The porto-potty should have smells coming off of it and some turds laying all around (also intended to make people laugh). This drawing would obviously be much smaller than the drawing for the back.
