There should be a formalized location in the city -- like a bazaar -- where players of a sufficient level can open a graphic design studio and sell services to clients in need.
Graphic design is a valuable skill in this city. Between needing art for you faction, profile, and newspaper ads, there's quite a demand.
Yes, the forum has a Graphics section. However, graphic design is such a rich part of the game experience, it deserves an official inclusion into the economy of the game instead of being a black market service based on word of mouth.
Thoughts, anyone? Improvements to this idea?
