I’ve had this idea rolling around in my head for a while now and have been thinking of a coherent way to present it. The basis of it would be addition to the LM, acquired through an upgraded LM.
It would be a notice board of sorts, where players could post “ads” of good they’re always accepting contracts for. Player would be able to list what commodity and a minimum price per unit they would accept. Something basic players could post would be ideal 
There could be weekly fees to keep the ad up, maybe even an option for PRO players to have a contract template that they could present for other to send them with minimal options.
Maybe even “buy” notices for player who always need a type of good and how much they’re willing to pay for it.
