I am trying to create "job" for a very small, specific sect of people. These people's bodies naturally generate and store an energy capable of creating temporal and physical discontinuities. Basically, they are capable of magic.  Due to a physical incongruity (their eyes are bio-luminescent and have patterns) the general populace knows that magic exists. That being said people who can wield magic are very rare, plus govern themselves very strictly, so magic (on a local scale) is heard of once, maybe twice a year. Altogether there are about 150 million mages in a world population of 4.5 billion.

The entire story (I hope) will be based on a singular group of islands about the size of Japan (the entire world is islands so wherever they go it will be island-y feel). The world has had enough time to advance to 21st century technology (of course aquatic tech is much further ahead while land-based travel is slightly behind). There are also monsters that can interact with mages, people that deal with magic on a regular basis, and inanimate objects. Mundanes can't see, feel, smell, hear, or taste these creatures. 

#The Question:#

What are conceivable jobs for a mage to hold?  (For the sake of convenience money is no issue.)
