Shetland Islands Quests

So, I've been thinking of some quests for the Shetland Islands, and I think there should only be around 5 or 6. There will be 3 main quests, as well as 2/3 side quests. For the main quest, I was thinking that there are some Norwegian invaders, and you have to drive them off (and if that isn't lore friendly, it can be pirates). There will be no reward for each individual main quest, but after you complete all three, you will receive a small house on the island. As for side quests, 1 could be involving finding some lost sheep (it seems that there is a lot of sheep farming in Shetland), and another involving a local dispute over a dead sheep, and a third, once you get your house, involving buying and raising some sheep. (hey, i like sheep )

Suggestions?
