Note: There is a ticker that ticks every second that reduces her earnings. To change from Lv1 to Lv2 stall, you need to buy 10k+ worth of stuff from her and wait 50min hour then buy a little from her again.

It is unknown at the moment how much gil per second is reduced. (source: Final Fantasy XI Guild Masters Guide Ver.101207 ISBN-10: 4797362294)
