Another thing to keep in mind about the dailies is all of them except the "resource gathering" ones and the Apexis Emanation quest can be done as a group.

So you only have to gather 5 Aether Rays with all of your guys in tow to get 11.99g * 5.

Fast way to make money and you can easily push the 4/5 primary dailies (Skettis bombing, Skettis Escort (9g, and only if uncamped really), Aether Rays, Forge Camp Bombing, Banish Demons) in under 30m depending on how busy your server is.

If you do all 5 of the dailies while 5-boxing it's a bit over 285g. If you don't care about the annoyance of having to do the Apexis Emanation question 5 times, make it 330g but you can probably make 45g with easier methods if you're running 5 toons

Getting access to the Netherwing dailies and doing the non-heroic/heroic dailies as part of your 5-manning will increase the gold quite a bit.
