Skyrim is a wonderful world of wonder, but sometimes you run out of that shiny fuel that keeps you chugging potions, buying that third house, that third replacement horse and, of course, more armor. Here's a little trick to make gold a non-issue.
Requirements!
-Access to an Arcane Enchanter.
-A crappy, though filled Soul Gem.
-A crappy weapon.
-Knowledge of any weapon enchanting recipe.
To before we start, the higher your enchanting is and the more points you've invested into the first enchanting perk the better.
To start, we need to find one of these. Petty Soul Gems are preferable, though any can work. Problem with the other gems are they're expensive and that just cuts into our profit margin. You can get these from your friendly, neighborhood mage-in-the-yarl's-house and you can fill it with any wolf out in the world. Why wolves? They're everywhere. You'll need either a weapon enchanted with the Soul Trap enchant, or you can just cast the Soul Trap spell on the wolf before you kill it. You can most likely get Soul Trap from that mage we talked about.
Now, you need a throw-away weapon. One that is going to be vendored anyway. Armor won't work here, since the whole point of this is to exploit the fact that you can adjust the power of a weapon enchant by lowering the charges to increase the damage(or max level of enemy affected) and the game just seems to think that more power equals more money.
Now, after selecting your Soul Gem and Weapon, got to the enchant section of the Arcane Enchanter menu and flip through your enchants. Select whichever has the highest worth at max power. For me it's Banish, but Turn Undead is nice and much more accessible.
Now, have fun with your new money-making strategy!
