Create an Illustration of our Product

I need an illustration of our product. We manufacturer dog beds that have 4 components: 1)memory foam; 2)supporting foam; 3) waterproof liner; and 4) washable outer cover. The product has 2" of memory foam, permantly glued to 3 inches of supporting foam. The a waterproof liner zips over the 2 layers of foam. Lastly the outer washable cover zips over the foams and liner. We need an illustration that will help potential customers understand, at a glance, what our beds are made of. Perhaps an exploded illustration of the 4 parts. Or a view with the 4 parts peeled back. This illustration MUST convey immediately upon viewing what makes up our dog beds. It needs to be a white background, with the 4 parts labeled, and in jpg format. It will be used in website copy.
