Dairy setup?

Y'all I have been pasteurizing my own milk for quite some time, but I've never gone past a few gallons a week, my neighbor who is a dairy farmer is going out of business and I would love to purchase one of his cows before he sells them all. That said, I am looking buying some equipment to milk and store roughly 46 gallons of milk a week. I would pasteurize it and further process it into other consumables. So, what equipment would you all recommend, I farm for a living but I have no experience on the equipment side of milking and my neighbor will help but I want to see if other folks have done this already and their setups!

1. What milker would you recommend (I aint got the time to do it by hand!!)
2. Storage?
3. Batch processor?
4. Possibly selling excess?
5. Simple, affordable setup for milking? (I can use a headgate and chute system I reckon, but is there a better method?)
   Thanks in advance!!!
