"Five coppers a day."
"Now that sounds reasonable. I also want that bow and some arrows."
"You have to buy the arrows and if anything you rent from me get damaged you will compensate me."
"Fair enough."
"Now come here with me for a moment. Look at this," the halfling pointed at several shops alongside the street that had a flat board with papers on it so any passerby could read them easily. The boards were put a little to the side of the doorways of the shops.
The papers had information on what beast they want hunted, what part should remain intact, old or young and how much they might pay for it. It didn't need anymore explanation, the monsters hunted in The Valley get sold here.
But to whom? That's why people put these boards so that hunter would know who wanted what, and make the exchange easier and simpler. It also gave the hunters a target for what was in demand in the market.
