Often the materials are based on a case that you will gain one skill point each craft. This won't happen, so you will have to buy a few extra materials while you are leveling your Outland Inscription.
If you are low on gold, I recommend you to try this Gold Making Guide, it can help you to make loads of gold.
If you are still leveling your character or you just started a new alt, I recommend you to use a leveling guide. You can level your character to level 120 in 8 days with this guide.
Approximate Materials Required:
Mill around 700 from these: Ancient Lichen, Dreaming Glory, Felweed, Mana Thistle, Netherbloom, Nightmare Vine, Ragveil, Terocone
Learning Outland Inscription
Go to Outland and find Loremaster Skosiris in Shattrath City. There will be a bunch of bookcases behind him, click on the Inscription bookcase and learn Outland Inscription.
If you choose the Aldor faction during one of the Outland quests, then you can't interact with these books, you have to visit Recorder Lidio in Shattrath City. (the fastest way to find these NPCs if you just ask a guard in the city for directions)

Nightborne characters have +15 Inscription skill because of their passive [Ancient History]. An extra 15 Inscription skill means recipes stay orange for 15 more points. You can save a lot of gold by doing lower level recipes for 15 more points.
