When I worked at Winchester, back in the early 70's, case and bullet manufacture was done on Bliss and Waterbury Farrell presses. These were gigantic, automated machines, with very complex tooling. case and bullet jacket cutoff was done on automated machinery designed by Winchester and manufactured in CT and had been in production for decades. You need to figure out what you'll manufacture and what you'll buy from whom. I sugggest that you'd be best off to purchase primers from a company that is already set up to manufacture those to your specs. As far as perishable tooling for making cases and bullets, (dies, punches, bunters, etc) again you'd be wise to find a vendor who could make these to your specs. Bliss and Waterbury Farrell are old US manufacturers now out of business but they both made machinery that would last--and probably could be purchased somewhere used. The tooling would have to be designed and made. You're looking into a complex process to make ammo from scratch. This goes way beyond buying anything from someone like RCBS, Dillon, Lee etc. Before you spend any amount of time and/or money on this, you may want to go to an existing ammo manufacturer (Winchester, Remington, Hornaday, etc) and get a plant tour if they'll give you one. You are talking volume manufacture here, with lots of operations--and lots of calibers requiring lots of tooling. No amount of CNC technology or Just-in-time production control will make this a simple and cheap enterprise, even today. Good luck!
