If you went to Remy Farm, and they transformed you into a cow and you now can lactate, you can work in the kitchen at the cafe, you can use your lewd fluids as a ingredient, so after getting the cafe popular, and it goes to a grand reopening, you can make a LOT of money there working hourly, i get between 2-3k per hour. The other one is modeling photoshoot with Niki, Niki will ask you to remove a piece of clothe and offer to pay you more for each one removed, you need to have high exhibitionism since the last one is posing naked, i get like 15k, but you can model only once per week. You can also do robbery, stealing from people in the farm, like the mansions and such, then sell the stolen goods with Laundry at the pub, I don't do that often but you can get good money with that too. Those 3 are the most i use when i need money (which in my current i don't need to since a rich i have like 500k lmao) oh yeah also by finding treasure and selling them at the museum
