This guide will be alittle dumb downed as if you're new as well, not going to be too detailed since it isn't that hard to figure out.
Start off by making any type of Novice, preferably once in which has 9 str, 9 agi, 9 dex. Go through the training grounds and get to Base level 12, job level 10. Once you're done with that go to the town Alberta and become a Merchant, merchant guild is located at the bottom left of Alberta. Once you're a Merchant there are many places to level at, preferable Poporing until around 25-30, at that level you could either continue soloing at other places or go to Louyang and find a mage/archer to run Mi gaos for. get yourself to level 52/40 or mainly just job 40. But when done, go to the town Geffen and become a Blacksmith, guild is located 4 o' clock direction from the center. Once you're a Blacksmith, locate the quest skill NPC to get the skill "Greed". Here is a url to a site that shows where the skill NPC is, you can really just follow the pictures if you can't read the site.

Once you have the skill, go to Orc Dungeon level 2, once there you will notice alot of Alchemist afk'ing their pets, and alot of loot on the ground, use greed over the loot, and it will pick it all up for you, doing so for a few hours will make you alot of zeny. Just OverCharge the loot at an NPC and now you got a good source of keeping the income flowing.
Not really a cheat or anything, but it's a good way to get yourself established in the game with some money and be able to afford your gears. Hope this helps, and good luck in your adventures!
