The only likely source of wild live rabbits I can think of would be to find someone who ferrets and ask them to catch you some live Bunnies. I'm not sure regards the legality of this though mate, you would have to look into it first I imagine. Plus there's a good reason landowners don't like rabbits on their land, they can be seriously destructive. They probably will not confine their excavations and eating habits to just your own property either, you would be potentially subjecting your neighbours to these problems too. Don't get me wrong, I love shooting rabbits and can see why you may think this would be a good idea, but honestly I think you're on a bit of a sticky wicket deliberately introducing pest species onto your own land bud. Hope that helps.
