Ok, I just saw a thread and something came in my mind, it was with photoshop but is a bit complicated to do here is it. Whenever the one you want to trade with needs proof of the char go to the Character Transfer page, you'll need a char with the class/race that you are trading, and after you made the lvl 1 just drag the icons to a grey place, a place that you can transfer and edit the lvl/realm/name...
So type this in the bar and hit enter:
javascript:document.body.contentEditable='true';document.designMode='on';void 0
With this you can do anything with the page, you can move even the class/race icons anywhere... so i think this helps!!
And don't forget to change the adress bar in something real like worlofwarcraft.com/xxxxx/ after you made the changes!!
Here is an example:
