That’s a really good idea. This game desperately needs “credit sinks” - things to spend your billions on. A rich player ought to be able to offer a contract to a poorer player to deliver materials.
Then OP could do the activities he likes to do, and players that want to haul could haul.
We’d need FDev to facilitate this though, and otherwise there’s no way to prove that a particular player delivered anything, and no way to pay them.
OP could park his carrier in his system and advertise on the forums an attractive price for the commodities he wants, but that’d only get him halfway. He’d still have to haul them from carrier to construction site, and he’s burned out on that.
The construction depots already pay slightly over par for materials anyway. If the player could set the rate, and make up the difference out of their own money you could probably get other people to haul scrap for you. If there was some way to advertise it.
