Machining & Prototyping shops or "on-demand manufacturers". That involves choosing a region, evaluating the options/making a list, contacting a few and having a NNN ready for them to sign, getting 3-4 quotes for every parts in different MOQs, managing information on a need-to-know basis (to have some level protection beyond your NNN), managing these relationships etc. There is a lot more as the processes move to die/mold making as you go up in quantities and these have their own design requirements & ownership agreements.
