Making money in Maplestory?

I'm a level 29 rogue and i want to become an in I am following the main maplestory guide on mapletip. But before i become an in I want to get new gloves, claws, and shoes. So far i made the shoes and claw, but while buying the materials from people I lost a bunch of money. I had 1.2 mil now I'm down to 800k. I have been doing kearning pq which gives you a lot of exp and items. So i was wondering how I can make some money, i know it shouldn't be too hard but i don't want to get it at level 30. So i don't want to train to get it or i wont have enough money when I am sin. I have some earrings level 30 and 20, also a dark scroll for bw, and a scrolls for shoes for dex 10%. Are any of these worth anything? Anyway any help would be great! thanks. p.s. don't call me a nerd.
