We have a wooden milking stand that my brother in law made for us. We always used to use a milking stand, and then having the goat higher up allowed us to sit on a chair to milk- much comfier. However, my brother in law wasn't that accustomed to the goats when he built the one we have now, and he made it too wide for that. So, we sit on the milking bench alongside the goat!
We use stainless steel milk cans- find they last better, and of course can be sterilised. We had to throw 2 milk cans out last year- small stainless steels with lids, which held about a gallon of milk. My mum had had them for over 30 years, and she got them second hand, so they do last well. We just milk two handed into the bucket which sits on the milking bench. We might use a jug to milk into for the last bit of milk at a show if we had a goat which was likely to kick the bucket over.
It does depend on the goat how long it takes to milk, and on you as well. The more practice you have the quicker, and more confident you generally become. Some goats are as easy as pie to milk, others can be hell on earth, even if you are experienced at milking. Even the most well behaved goat can occasionally have a strop, or be upset and manage to kick the bucket over (and that somehow manages to happen at a show).
You can buy milking stands/benches online from Ascott Smallholding supplies, but it's not too hard to put one together that suits you. Use a small seive (tea strainer) and milk filters to strain through the milk, we don't pasturise. Store it in the fridge in plastic or pottery jugs, or plastic 2 litres bottles. If freezing, freeze in either 2 litre plastic bottles, or in a 2 litre ice cream tub. Once frozen, the milk can be tipped out of the tub, and the tub reused to freeze another block of milk. The advantage of this is that if you freeze a lot to feed orphan lambs, calf's etc, then it stores neater in the freezer.
