Hi Paul - what a story and glad to see how well you've dealt with your issues.
I think you can do real well with delivery services...there are a number of eG-ers who do.
Check out Wild Fork - their prices are some of the most reasonable, and their selection is deep (though much, as you mention, from Australia). My favorite lamb available commercially tends to come from Colorado...https://wildforkfoods.com/collections/lamb/
D'artagnan has lovely stuff, and charges for it...https://www.dartagnan.com/leg-of-lamb-bone-in-american/product/FLDLE002-1.html?bcgid=lamb But you can often do well on a first order.
I'm surprised your butcher in Madison can't get Colorado lamb. What about at your Whole Foods?
