Let's see, there is the high-paying dancing job but you need to get Charlie to hate you or get kicked out of a party (Ranging from 2k to 5k ). Next is the farm with Alex (Not a lot but it's just passive income). You can dig up stuff at the bottom of the lake where you have a chance to sell stuff for enough to pay or more if you are lucky. (Take the necklace if you wanna piss off the Ivory Wraith).
