To get a lot of money get a guy with alot of good items or money (leave the existing file). Start a new game(on 2 player it doesnt matter if you only wanna play one player) and import the player (the good one, we will call him goody). Drop all goodys items and buy stuff with the money he has got(drop the items he buys as well) and let the crummy player (lets call him player 1) pick them up. Then get player 1 to sell all the items he has got. Then import the other crummy player(lets call him player 2). Then you import goody and get rid of player 2. Drop all of goodys items again and let player one pick them up. Kepp doing this until you get alot of money.(spend it on potions/good armour or good weapons)
