The economic system of 4e is completely and utterly broken unfortunately and doesn't really support crafts and professions.
One of the most interesting campaigns I ran was where the players gained a deed for a small general store. At that point the planned adventures took a turn, as the players decided that they wanted to get the store up and running so they could earn money on it.
Many of their encounters involved bandits attacking their caravans with import or adventurers to gain favors. For instance by earning favors from the general of the nearby militia they were able to earn exclusive rights on all equipment to the military, from rations to weaponry, armor and horses. Eventually they expanded, doing adventures to dig up dirt on other businesses or setting up things so they could acquire the non-corrupt businesses rather cheaply. Which by the campaigns end led to them being who everybody came to when they needed money.
The point is that if the players really put an effort into earning it, they should be able to get a larger amount of wealth than if they simply do adventurers for whoever pays them the most. But 4e lacks the economics to handle stuff like that, everything is extremely limited in scope and your character can basically only go into dungeons and back to the city to use their gold to enchant new items or disenchant old items.
