You got a good problem going, its usually the lack of money
You can try do the western union thing, but it would have to be small amounts from random locations.
I know this cause I do check cashing and everything western union for my parents.
Also the limitation for 1 transaction should be less then 9,000 etc. Anything though that brings suspicious behavior have to report to FinCen.
note:
The better way would probably at a certain point, get a legit business going to clean the old laundered money (under the table money) to match yearly earnings.
