Really hoping that the market will change on the tick. The port is on a body with a refinery hub and two orbiting mining installations and a Coriolis which has an extraction economy. There's only 2 slots on the body so cannot build any more there. The body orbits a gas giant with a pristing metallic ring. I built the port in a large crater which has lava and steam 
Took 216237T almost all one jump away from my bubble system. And of course the 6 T3 construction points required a bunch of other construction including initial and second Coriolis, some security and agricultural, mining installations and a couple of refinery hubs.
