Sorry if any of these two ideas have been suggested before.
Alchemist/Wizard/Brewer - Where you make potions. You get get a certain amount for each potion you make
Enchanter - Enchant books, get more money for a higher enchant level.
Baker - Bake bread or make cake, or make other foods.
Armor maker (or something) - Make armor, earn meebles. If you make diamond armor you get lots of money, leather is just a little etc...
Add any more ideas to these suggestions :)
