Enchanting can be a very good way to make gold. Every time someone gets an upgrade, the first thing they do is see whether there's an enchant they could put on it, and if so, either have someone enchant it in a trade window, or buy a scroll from the AH.
The first thing you'll need to know if you're going to get into the scroll market is that it's not a good idea to use the default interface. You will face challenges that it is simply not equipped to handle. Chiefly:
- Knowing whether a scroll is profitable
- Knowing whether you already have scrolls made and for sale
