How about:
Car Impounder.
-Add parking places to the map. If you don't park your car in the parking space, your car could get impounded. A truck yard would be necessary within the map to store the impounded cars. To retrieve your car, you'd need to speak with an NPC, and it would cost you $10,000 to retrieve your car. The person that impounded the vehicle would receive $8,000.

That job would also bring a small cash sink, which we could use.
