Ok so I'm going to be sharing with you my spreadsheet for calculating cost/revenue/profit when it comes to making the epic shoulder enchants.
This is where I started making my gold and it's a great place to start working your way into the auction house. It's a small group of items which you can watch without hassle.

Download and save (I have disabled editing on the google hosted spreadsheet so everyone can get their own copy).
Items in blue are for you to change!
This will tell you if it's profitable to be working inscription and other than your time spent milling/crafting it's quite quick and easy gold.
Let me know how you found it and I might upload my other spreadsheets!
