To use it as an auctioneer, send all your auctionable items from your alts to your bank alt, and organize all your auctions from this character. This saves your time spent on auction house management, focuses all your income to one character and allows for easier overview of your cash flow. Consider using an alt management addon to be able to access all information about your alts from your bank character. One such addon is Altoholic
Go to https://www.tradeskillmaster.com/pets/compare to compare prices of different servers. I’ve done this a lot, and I’ve bought pets for a few hundred gold on a server, transferred it to my main server and sold for 10k gold and more. You also need to buy cheap pets on your main server to transfer to other servers so that you can build up a bit of gold on other servers so that you can buy pets.
This spot actually kicks BOOTAY. And I only say that because it's so hidden, unique and quirky that I had to add it to this list, despite it being a method rather than a farm. Generally what you want to do is some sneaky arbitrage. We'll be buying the items Royal olive, Dalapeno Pepper, River onion, and Muskenbutter from the vendor for 2g – and reselling them to the AH for 4g+. This is an awesome way to take advantage of players laziness and the demanding reagent requirements for some of the higher end recipes. By selling from the vendor to AH, you can make easy gold – in fact I suspect most cooks do not know these reagents can be purchased from NPC's.
There's a good chance you can buy the raw materials for 25% - 75% of the going rate of the finished item, or mine them for free. The fee for an 8 hour auction is only 1 silver, so you can afford to re-auction rods that don't sell the first time. Be careful of making too many rods or other parts of a kind at once, though, as you may get stuck with them for a long time when others produce the same item and set a cheaper price to it.
Allied races are variants of existing races. The Void Elves are a version of Night Elves, while the Highmount Tauren are, you guessed it, a version of the Tauren. Four allied races are already in the game before launch and two more, the Dark Iron Dwarves and Mag’har Orcs, were added after Battle for Azeroth launched. Each Allied Race has its own racial abilities. You can also unlock a heritage armor set by leveling any Allied Race to the level cap.
