Quick money events? (Patreon)

While testing the game build I've noticed that the girls might be lacking 20-30$ for something essential all the time (like buying a Gym subscription), so I'm thinking about a quick money-grab activity for each girl, but I don't have a clear idea what kind of activity should that be. Any ideas? For Lana, I thought she could do some Vault glory hole event when her Urge is at max and she needs cash. But no idea about Casey.

Here I mean a quick event that does not require a long story or multiple assets to draw (ideally - just one scene for each girl).
