I could sponsor this event by donating 10mio of my own cash to the employer and organize the event with backstories, commodity list with prices, book keeping and general stuff forum-wise, but I don't have time or the needed RP to be the employer alone.
The problem with Bretonia being the client is that there is no very active trading faction in it. And using completely indies with their rag-tag assortment of IDs and reps would make obtaining some of the hard to get stuff too easily. It would be ok, for the faction hired for the job to use third party to obtain stuff, but the faction should not have access to all the commodities. Or indies having the proper RP to assists the trading faction.
Fundamentally this event needs a rather active authority and trading faction in the same house.
So any major house authorities willing to step in as an employer or trading faction responsible for obtaining the goods? I can screenwrite this for you. Once we get to know these players the enemies are clear. Also any pirate is sure to rob the transports blind if given chance, so it's under trading factions discretion to hire help if they feel they need it.
The main thing for the traders is not to make money, but have fun. But of course maximum profiting from this should be a major goal.
