Siobhain should be at stable mid-to-high class in regards to income. Given that she's rather frugal by nature and subsisted off her teacher for the better part of her life, she was fairly well off leaving Ul'dah. With the income she accumulated from her 'practice' in the arenas, and the odd jobs she did to build repoire during her training to become a paladin, as well as her inheritance from her teacher after he died, Sio's had quite a bit by way of funds before she even began her blacksmithing work. However a large portion of this wealth, as it were, will be invested in the linkshell that she and a number of others are putting together.
After all is said and done, maintaining her blacksmithing work and the odd leve job, she'll probably still be at a comfortable middle class.
