if u tell me what realm your on i can send u cash and theres lots of ways to get gold 1 by using the AH (Auction House)
your’ll make lots of cash 2nd by doing quests and killing monsters and 3rd running instinces suchs as DeadMines
farm random items from monsters you can kill easily, you won’t make us much starting off, but you will get levels faster, which allows you to kill better things, and the items you get only sell for more with the more you have.
There are several ways to make money, At your level though you don’t have many options. I would recomend going on Instance runs and selling any BoE you get on the AH. Your a good level for VC (The Dead Mines) and WC (Wailing Caverns) In a few levels you’ll be ready fro SFK (Shadow Fang Keep)
Pick a profession such as Mining/Skinning or Herb/Skinning - NOT Mining/Herb because you can only track 1 type at a time If you choose to go Mining - Do not convert it to a bar unless your server pays higher prices for Bars.
I would also recomend getting the “Auctioneer” addon. There is a BTMScanner that goes with it which you can set it to look for deals, buy it then turn around and resell it.
The AH is a trap that many people fall into where they think “i need gear” so they go there to Buy it… yeah it’s quick and fast but you will loose a lot of gold that way. Before you know it you’ll be lvl 30 and short on funds for your mount.
I’m not sure what kind of Server you play on - I play on a PVE so farming is a lot easier - dont have to watch my back when Im farming.
If you have questions feel free to msg me and I’ll help you as best as I can.
