Apologies if you already know but there is a load of easy money to be made from just flying around.
Going to each bonfire nets you 6g but even better going to the Horde ones nets you 12g each.
Use this map Outlands Bonfires and just fly to the red dots, not only did I make about 130g in 20 mins, I got loads of blossoms from the fires that can be exchanged for the top food (e.g. +23 spell damage or +44 healing) plus I got Motes from Clouds on the way (being an engineer) but mining would be good here too.
You can do exactly the same thing in the other continents, see wowwiki for more maps (but no flying mount makes that a bit tedious)
However if you can't be bothered just aim for neutral cities as they always have 2 near each other (area 52/everlook/silithus/booty/east plague etc.)
By the way I think this all ends on Friday so move quick.
