I recently power leveled enchanting from 1 - 450 and decided to record it all in a video.
Enchanting is probably one of the most expensive professions to level, it took 7,200g to level it but I did choose expensive recipes to make from 350 - 450 based on the profit return I would get to compensate. The scrolls I created from 350 - 450 are valued at 10,525g which will give me a profit of 3,336g for leveling enchanting.

Part 1 - 1 - 275
Part 2: 275 - 450
The key to make enchanting profitable to level is by choosing the right enchants to make from 350 - 450. In order to do that you need to makes ones that are profitable for your market.
I created a spreadsheet where you can input your servers material costs and servers scroll prices to determine which scrolls are the most profitable to level up with. You can download it here:
