You’re looking at an extremely old problem: manufacturing. There are easily a hundred-thousand millionaires who only built things others first created, at scale. The secret is to look through manufacturers’ conferences. Don’t think your item isn’t “big enough” to be built by a big corporation- expect 10,000$US/Euro would be enough to build an assembly line, then cost-or-so to create each one. Distribution centers would love to help you handle in-state/country shipping, too. Find them alongside the manufacturers at conferences— there are 10 a year in the USA that literally publish all the manufacturers for this reason! Good luck!

i have no clue what i just read. an SMT assembly line easily costs 500K. for 10K you can just buy some lab tools for prototyping.

Building your own assembly line is not a 500k$ problem. You’re referring to a splice-overlay method, which takes 200 machines, and that’s not even a very efficient method.

Do it by hand, that’s the most expensive it should be. Then improve efficiency one-part at a time.
