Some organized suggestions for those of Ferengi descent.
No-maintenance race:
-Shipping service. For long trips, other players can save money by hiring you to fly their ships to various places.
-"Tow Truck" service. Damaged engines? Out of gas? Don't destroy that ship or spend big maintenance on it, get it towed home cheaply!
-Long-term storage. Need to save for a rainy day, and don't want to spend unmothball costs? Park the ship in a no-maintenance lot, and get it back on two turns notice!
Generic Racial/Unique Tech researched:
-Build custom starships for other races.
-Construct special facilities on planets.
Temporal Tech:
-Emergency building of ships for those who want it now. (works best for large ships/bulk buys, and in galaxies with WP highways for fast delivery)
Strategic Location:
-Charge for fast repairs of combat damage on site.
-Sell supplies for ships and fleets. A good price might be 1 mineral for 10 supply points.
Vast Resource Storage Capacity:
-Act as a bank, loaning resources, and opening savings accounts.
Big Racial Happiness Bonus:
-Put down riots (You could charge a lot for this, if the riots are spreading)
Any race:
-Sell units, which you can store for free until sold. (psst! You wanna buy 250 "Firestorm" tanks?

) Just swap cheapo cargo ships with your customer.
-Sell custom-built ships for those players who need ships quickly.
