This is my first guide so feel free to leave some feedback!
This is how I turned 2-3k into 10-11k with 1 hours work and a bit of patience.
First of you are going to want some gems like and Bassically just buy whatever gems you need to make 450 ilvl necks and fingers, on my server sell well so I make around 3 of them the rest of the ilvl 450 gear I only make one unless I notice they are selling well by checking www.wowuction.com
Now you should have around 10 of the 450 rings and necks to sell. Now for the inscription part.
With the DMF coming up I have been making one DMFC a day by using my Scroll of wisdom CD, It costs around 1k to make a DMFC but mine having been selling for around 2k and its not even the DMF yet. So make sure you make your daily DMFC! The rest of my gold I use to make the blue shoulder enchants and the occasional purple one but only if there is profit to be made (Only make these is starlight ink isn't too expensive)!
Once you have all your shoulder enchants and rings and necks you should have around 11k of stuff in your bags depending on your server (ONLY MAKE THESE ITEMS IF THERE IS PROFIT TO BE MADE CHECK YOUR SERVERS www.wowuction.com TO CHECK) Now go to your local auction house and list them I use auctionator to list my items and the Trade Skill Master tab to check my total cost of auctions in the AH. You can use the "More" tab in auctionator to check for undercuts and then cancel all auctions that have been undercut and then relist (only do this if the undercut isn't stupid)
And there you have it a bit more cash in your mail box to loot!
