I think some basic jobs would be interesting. I'm not sure how viable they all are, but I can think of the following off the top of my head:
1. Builder (paid to place blocks)
2. Lumberjack (paid to chop trees)
3. Chef (paid to cook things)
4. Quarrier (paid to mine stone only)
5. Smelter (paid to smelt things)
I'll add more if I can think of some. Thanks!
