Legal work isn't worth it, just by looking at the market prices people automatically go to illegal, also look at the map every legal work is so far away from processors so you would have to drive a bunch just to get a couple thousand dollars which is not worth it.
I bought a truck just to try and do legal work but as soon as people see theres a truck they start following it and try robbing it, and good Civs can't really defend themselfs with rooks or pdw's then they get the manslaughter charge and police don't believe it was self defense, they have to pay the 20k for the ticket and now they wasted all the money they earned in that legal run trip
