Im thinking you could have levels of vault crime's.

Launder 5k to 100k of vault money.Takes 3 days to complete and could return upto 3 times your outlay.Chance of jail and swat if failed + loss of outlay

Playing the stock market would be a daily business.Small wins and small losses.No chance of jail or swat.

Gang protection racket.Invest 10k to 200k to fund this weeks operations.Hope no-one betrays you!

Drug and weapons trade's.Your gang meets another for the trade off.Does it run smoothly? 10k to 200k invested.

These crimes would not affect the organized criming.They would be different as they take your hard earned money.
