If you want my advice, don't cheat. It'll completely ruin the game for you.
If you want money, you should rob rich people. Nah, you don't need the pickpocket skill, you want to rob their houses instead. Rich people don't carry around anything of much value anyway. The most valuable stuff is in their house. Only thing you have to make sure is that they don't see you stealing anything. Use shadow potions, or hiding skills, they help...
Try and steal weapons and armour, and sell them for money.
Places to look for stealing:
-Stormfist castle armoury.
-Sir Dante's house (not sure if he has much)
-Verdistis Town Watch Armoury.
-Rivertown barracks. (When you ask General Alexis, or whats her name, for weapons, she'll give you access to the armoury. Make good use of this, and steal everything :P)
-Deserted Imp Castle underground treasure room. (Guarded by very strong enemies I'm afraid)
-Rivertown Sewers (south-east there is treasure. You need telekinesis to reach it though. Or just drop your pyramid in there.)
-Verdistis Sewers (You can find 10000 gold in there)
Then, here's a tip: Always sell your goods to Geoff in Ars Magicana, he always carries around 50000 gold. And try to be friendly to him. This won't get you extra cash, but he'll lower his prices a bit.
And another tip: Sell minor and small charms, don't use them. They're not worth it, especially because once you use one, it's permanent. Rather you use a silver or gold charm instead.
