I'm thinking ground rope and short leads. I've seen something similar done with pack goats. scatterign food on the rope helps train them to it, they'll wait more patiently if they know the ritual includes food sometime. even just a snack.
But that's a herd that's been allowed to go wild and we were primarily milking them for their relief. They're anarchist goats. If I stay longer on the farm (which is not mine) I may give it a go taming and training them, though. Should be fun :D
