For a level 29 as yourself, a great spot for you which can also raise a potential craft would be...
Farming sheepskins for either Sheep leather(1 sheep skin, 1 dark crystal, 1 windy tea leaf, 1 distilled water), or sheep wool(2 sheepskins, 1 wind crystal). But sell for about 9-10k on Shiva last time I tried it. You can also use lightning crystals to de-synth cesti's (very low cost, but 60% failure rate on de-synth).
Another low thing to be done is possibly beeswax(dont remember recipe) which is also found prevalent in konschtat from beehive chips, with fire crystals.
For those of you a bit higher level, bcnm40 CAN be a great money maker. Its luck and skill. Drops arent guaranteed but can earn you some fast cash in a good group. or Farming tigers in batallia downs for fangs/hides.
Just check the AH for a fair priced item, find the monster who drops and try to make a low recipe for it.
