Norg is very remote, because of this, it's trading potential is rarely utilized. A lot of odd equipment for Ninjas especially can be purchased here. The Norg AH is linked to the Bastok AH.
Kunai is a good start, though available for a similar price at the Tenshodo HQ. These daggers sell for a premium in Bastok since the Ninja Flag quest ends there. I made about 1200 down to 600/pop for these, though the price has since stabilized at an approximately 400g profit.
Shinobi-gatana are usually a fast sell (for a single-class weapon) as they are used in crafting higher level katanas. I could get about 1.3k profit on these, and the price did not drop from overstock. The alchemy guild is in Bastok and thus a lot of Alchemists live there, which is good for you since you can automatically list your items in the AH after purchasing in Norg. Even with a markup, Alchemists make good money on katanas. +1 katanas sell for insane money, so many alchemists are attracted to this particular route.
Nodachi are a big big moneymaker for me for some reason, they don't seem to drop to Norg price like other Great Katana. This is only true for the Bastok AH.
Ninja scrolls are a popular trading item, and sometimes (if the other local traders have moved up to larger fare) you can make good money reselling scrolls. Hyoton and Raiton are not available in Jeuno, so favor these. Scroll prices can be arbitrary and fickle, so check your AH before buying scroll stock, unless you don't mind learning the spells yourself.
Ninja tools are sometimes tradable, though the prices fluctuate very wildly for reasons I do not understand. Sometimes I see them for 30/each for all six elemental tools, which is a price I can make about 20/each off of. Sometimes, though, the tools go for upwards of 70/each, which obviously is a bad deal.
Like almost all item trading, Norg item trading is not lightning speed, and it has no future. However, trading these items casually over a few weeks can make you quite a bit of money, perhaps enough to get you up to level 40-45.
