start off by just buying leather at poca cosa and reselling it at cagnac. buy shoes there and bring them to poca cosa. do this so you can get a bunch of trips in quickly. make sure and kill off robbers that have guns and take them. do not buy weapons. take them from the robbers. dont worry about people at first because you alone can kill 4-5 robbers by yourself. once you have about 8-10 well armed people head out to hara. but have lots of money! you want to buy their 7 jewelry and resell it at just about anywhere for like a 500-1000% mark up! the rest you will have to figure out on your own ;)
go to verdammer platz for the patrol ending. but do it without the government sniper. also you cant have attacked any caravans it seems. when i went they chased me out saying i had attacked caravans. oh and stay away from the caravan x ... bad news attacking that one because then it gets published in the newspaper.
for the gov ending go to the capital, Qubba i think. then to fort gokks. then down to verdammer platz. dont wory about haggling him up for 100k because it wont matter either way.
