I'd say don't alch... Superheat. You train a skill other than mage + you can actually profit from it. The exp isn't bad either around 35-65k a hour depending on what your superheating. There's a guide on Zybez I believe along with a google table to show you what bars are profit, and what you lose from others. While you superheat you could also buy the stuff you need to use the moltenglass lunar spell which can make 600-1m an hour if I remember correctly. Takes a while to get the stuff on the G.E but while your waiting it's worth the effort.
Slayer is a great option for moneymaking. Even if you have maxed melee's. Godwars is always good. with 130m wealth you could easily get great gear for solo bandos. Which in my experience can make 20m a day if your dedicated to it. Corp is horrible you spend countless hour trying to snipe a sigil then all the sudden one drops and guess what... Some other kid gets it. Makes you want to /slash wrists.
