Lets not nerf money making even more.
Buff Trading!
Of course factions could sponser traders, give them competitive rates.
Would actually work quite well in this system:
Faction puts out a contract requiring so many goods in this amount of time.
Traders and trading factions can either fulfil the contract independently, bit by bit, or attempt to claim the entire contract on the assurance of fulfilling the demand entirely.
The traders show their evidence on the forums, the factions pay out.
The admins then give the factions the money paid out, plus a little extra.
Admin moneys can be done every fortnight or longer.
