As far as I know he only gives out the delivery missions (well, as generic quests anyway).
Basically, you pick up a cargo, deliver it to the city, talk to the store owner there, and mission is over.
Things to watch out for:
- Rats - if they destroy cargo you're carrying you must make up for the difference by buying all that was destroyed - and that can be a really expensive (if that good is illegal in the destination city especially) or annoying (if that good is scarce in destination city - it can take couple of days to make up for all the losses)
- Being on time - besides from not getting reward if you're late, nation that controls the city you had to deliver goods to puts up a bounty on your head, you suffer reputation loss (hero's reputation), and you'll have to pay the penalties for the cargo (you must deliver the goods anyway, and on top of that you have to pay the fine, but I'm not exactly sure if the fine is cash equivalent of cargo value, or twice the cargo value - managed to mock up only once hehehehe), also, until you don't deliver the cargo and pay the fines you cannot get another delivery job from any other store owners.
Note: Deliveries are only to friendly ports, so for example if you take a job at one of the pirate colonies, it will only send you to another pirate colony.
