OMG...
What we need is a Sub-universe of all nomad stuff and the Nomads can trade/smuggle
within their little universe homeworld, and thats how they make "money"
to pay for their wars against us.!
(just kidding, thats a stupid idea)
I believe that Mining stuff in a highly radioactive place, constantly being raided by gunboats and bomber Pirates and travelling over 150K to drop off the "loot" (also the pirates have mined off the area somehow, so you'll take some damage flying through a minefield, think those random 1 at time occurence mines in one of the... Omega? systems in Vanilla, in the Bounty Hunter, Hessian, Corsair contested space.)
Should make like 100M an hour for each person involved.
(You'd need like...
A miner, Two Repair ships, A SuperTransport and Two Cruisers)
Miner + Repair ship + Cruiser stick together in the field,
SuperTransport + Repair ship + Cruiser fly back to base,
Sell loot, buy each a full load of B/Bs and fly back,
to resupply the other people with B/Bs and pickup another load of mined material.
This whole thing sounds completely ridiculous, but hey, its a Teamwork-based and highly risky system, so it should be worth 100M/per Hour/per Participant.
