Let me suggest that you always keep your weapon updated. Buy this weapon as it's only 33k.

Rank 20 Leves and above are a good way to bring in some income. If you can, port to each city and complete the regional rank 20 leves (there are 3 in each city and you can do 8 of them a reset). As for farming, do sheepskin near LL. In La Noscea the coordinates are (25, 38). They sell for about 5k+ a pop and have a 20% drop rate.
