Well i think the best way would propably a middleman. The Customer contacts the middleman and established the Details of the Contract. The Middleman then posts the Contract in a special thread or spreads it among the bandits, the first who brings proof gets the Reward. For this the middleman meets up with the customer at a specified point without any weapons of his own. the Customer hands the Middleman the reward and at some different place The Middleman will hand the Contractor the reward. That actually sounds fun, if interest is there i would set up a seperate thread and volunteer as Middleman...
