A 100k commercial shipyard is pretty easy to create. It’s the same cost and time as a 10k military shipyard. My commercial station designs are usually 125k to 140k tons (miner, harvester, terraformer, etc.) and all built in shipyards. For example:
The above mining design includes twenty-five mining modules, so you can already build a small, mobile orbital miner with cargo capacity that can be built from a brand new commercial shipyard with no capacity increase. I’m not sure why you would need to build smaller than that. The tiny cargo hold will hold up to twenty years of production from this ship.
