When you get into this level of self-sufficiency, there are a lot of specialized tools--part of the reason things like grinding flour were some of the first to be centralized.
Kitchenaid or Bosch mixers have attachments to do most of these things. They usually are not the best tool, but adequate for occasional use.

If you are serious, I would invest in a dedicated flour mill. They need to be a fairly heavy machine to get the job done well and last.
You can invest in a chop rite sausage stuffer and get the press basket, then it can be used for wine, honeycomb, cheese, etc.
There are solutions if you think outside the box, but sometimes the dedicated tool is worth the investment for time savings.
