I need 2,338,562g to finish my current quest e_e

I've been vending, but lost a ton of gold on a few bad vends, so I'm back down to 600k.

I'm out of good fast ways to make money without having Stapled's market bot

So, how do you guys recommend I make 2.3m quickly? Anyone know of some good fast methods? Nothing long term like hoarding though, and nothing requiring me to spend real money, I'd prefer not to.
