Window Stencil

We have a rural business in Seymour Australia. We have a logo but would like to paint a big painting to incorporate our logo and name into the painted result - that could be a stencil for the window - or painted on the wall. I have a logo of our local show/fair that lets you know what we were thinking - along with the present logo -that we use on business cards etc. We would have to be careful copyright so the more realistic the animals are the better.
