Firstoff, this is not about the fortune cards.
But for your information: You can flip Mysterious Fortune Card & get one of the following cards: fortune card - Wowhead Search
If you are very lucky, you can get a epic card, which vendors for 5000g
Also you could buy those 18.000gold orbs in Pandaria for the jewel panthers, but you'll have a hard time to sell them w/o making loss.
Now to the actual topic:
You can vendor the following items for 18g, 75s
Crane Wing Inscription - Item - World of Warcraft
Ox Horn Inscription - Item - World of Warcraft
Tiger Claw Inscription - Item - World of Warcraft
Tiger Fang Inscription - Item - World of Warcraft
One stack of these entchants is worth 375g at any vendor.
With the following bag, Royal Scribe's Satchel, you can get 36stacks in this bag.
375g*36 = 13500g in each bag.
You can have 11 of those Royal Scribe's Satchel.
13500g*11 = 148500g
Ofcouse it can be less [depending on your overall bag space(funitems, style gear, t-sets)] or even more gold [standard bags(about 36 bag spaces)].
Extra infos:
1) Making 160 shoulder entchants (3000g worth) took me about 45minutes.
2) Aslong you dont pay more than 1g60s each herb, you'll make even profit.
3) Names of the pandaria herbs:
3,1) Silkweed
3,2) Rain Poppy
3,3) Green Tea Leaf
3,4) Snow Lily
3,5) Fool's Cap (probably useless, its not cheap on any realm)
4) You can sell the star light ink for about 400-800g stack (depending on realm)
