Just to expand upon this, as service-style companies are not as easy to tier up as commercial/manufacturing ones, a good way to run and grow a company of this kind would be to gain contracts with people/factions/even other companies who need the minerals. Tenloss looking to make a fleet of ships? Offer to go out and harvest the raw materials (and maybe even process it if you want that part of your thing), do so, and bam, a contract is done. For submission requirements (I admittedly don't 100% know how it works these days, I'm going off an older version of company tiers) I actually tended toward making droids/drones/etc to assist in the mining of resources.
Good luck with whatever it is you have planned! I'd offer to sell you blueprints to a few of my old toys but they're likely archaic compared to what's being made these days!
