Which Craft I'm Looking?

Well well, i'm looking a craft where I can farm the materials (i like this *.*) and get profit. (no talking about millions but any for can survive)

I have a thf75, I think the best options are leathercraft, bonecraft, alchemy, but which with take a time farming make a profit, even at level 60+

I want to dedicate a 1 in particular, recommendations?

Leathercraft is your best bet.

Leathercraft 1-90 Every synth is profitable. You can farm any mats easily. Took me about 2 months to get into the 70s. Most expensive synth was... 4k. I started with about 20k to invest in it as well.
