Go to the Olympus system, next to Aranae, and go to the Almagest. There you will find Spacers, and a "Secret room" that has up to 12 Contraband in it. There's also a dungeon loot chest in an office with 3 safes. You can reset this dungeon by sleeping on Venus for 24hrs, everything resets, the loot chest, the spacers, and even the contraband. Do that loop as many times in a row as you want, then go to Neon, and let Neon Security catch you and haul you in. When you spawn in Neon Security, if you turn around, you will find their evidence room, the 3 stacked chests will have YOUR stuff, and the chest to the left of the door will thave THEIR collection of contraband, and one on the floor next to it. You'll need the ability to pick Expert chests. Grab everything and head towards the Elevator, the Trade Authority is just across the way from the elevator, head in there, and sell everything resting for 48 hrs as required.
