Native American Rastor and Vector

I am looking for Native American designs. The purpose of these designs will be used to cut out images using a laser. Raster will be used to imprint the design on wood followed by a vector to cut the image from the wood. The images should be fairly small about 1-3 inches. I have a need also for larger images with sayings such as Chief Seattle "Earth does not belong to us; we belong to the Earth" and other famous Native American quotes. These are expected to be 8x12 or 12x18 inches. They need to be of good taste and not offensive to Native Americans. Please do not submit any caricatures of people. I am looking for other designs for example: Arrow heads, eagle feathers, medicine wheel, bear paw print, wolves, and many nature based designs. All designs will be in black and white. Please no color. We use Coral Draw to send images to the laser.
