Found a good quest today it starts and ends in Nettleville Hovel.
Quest Name: Verth's Delivery
Steps.
1/ Find Verth
2/ see his brother at the docks
3/ don't return to Verth, speak to Captain Hastings instead .... reward is a 8slot bag and 45copper.
For information on a 6 slots bag as well:
This is done on the Isle of Refuge (training area) a 6 slot bag drops off the Goblin Captain at the goblin camp in the SW corner ... one with the crates.
Aparently it can drop off other nameds as well ... Ginga has only seen it drop of the Goblin Captain however.
gobin supply captain, warmonger and seige planer all drop the goblin bag but it is lore

Oh one more bag related tip - you can build elm boxes with 5-8 slots as a way to skill up tradeskills. They weigh a ton so they are really only suitable for the bank, but you get more slots then you do from the bags you can make at the same level.
