Squirrels needed!

Hey yall! Chris here. Mike and I are teaching a hide tanning/primitive cooking intensive and we're going to need about 20 squirrels.. if any of you live in a state in which it's legal to kill squirrels in your yard, and you have a knack for/and/or enjoy hunting, any help would be great! Kind of a strange question, I know, but I figured I'd ask! If you get any, just chuck the whole thing in your freezer. Try for the head, we want as little holes in the hides as possible. Also keep in mind that kids will be around these so don't use your buck shot.. the less gruesome, the better :]
