I would think of starting a vending machine business . Maybe even create a business account. Vending machines deal with majority cash. It won’t happen over night.
Buy one with money from your normal bank account.
Buy the stuff to put in it, but unload that by selling to someone who can use it. Store owner or other vending machine owner.
Claim as.much per.day as an above average vending.machine would make.
Until you wash enough to buy more machines.
Keep it up til you can wash all the cash in a reasonable amount of time.
By then, you might want to actually.run the business after you finish the wash
