I stumbled across this mod today that may help a bit :blush: (crossing fingers and toes).

I haven't tested yet but it's description says:
How to earn Money (Does not work on residential lots):
With the buyable Computer or Cash Register. Like my Freelancer Mod, these will let you collect Money every 24 hrs. Like the Freelancer Mod the outcome is random and depends on your charisma level
Bartending. When Sims order a drink you will get a random Money loot no matter if you are the bartender or a NPC. Set the Hire Limit from 1 to 3 Barkeeper
EspressoBar. If you own a Café you will get Money when sims order Food or Drinks. Set the Hire Limit from 1 to 2 Barista
Looks promising!!
