Joy of Life Challenge - Gen3 income

I'm playing the Joy of Life Challenge by simelune and just about to move to gen 3, which is a vampire generation. Having never played with vampire Sims I'm really looking forward to it, however the challenge rules do not give any guidelines for how this generation should make money.

I'd like to use a rundown manor from the Gallery and renovate it over time, but that will need a way to make income and traditional careers do not feel in spirit with the vampire theme for this gen.

Anyone else playing the Joy of Life Challenge and came up with a way to make money in a way that stays true to vampire life? 🧛

My Sims are only teens right now so I have time to work something out, but would love some suggestions 😊
