well bud, in my opinion i found beehive chips to be nice quick sale for 3k or so, but i think ud be good at something like tree cutting or heck maybe lizard skins. skins go for like 8k a stack, and as 50 mnk u can kill alot of lizards quick, dunes has those 'aint nobody touching these so might as well farm them' lizards up near gustav tunnel beach.
Mining it'd be best to have sneak, but then again ur 50, im not. Gusgen is nice once u figure out the points, and palboraugh is good too. Yughott's tunnel has some good ore also. But, to have better chance you'd need to field tunic and gear. Seriously i think you'd do well farming sand bats in dunes for fangs while killing those lizards, or messing up every crawler in odin for silk and such. But thats just me, my highest is 33 so..
