Moving to a different bank isn't an easy task.
of course it is:
Just go close the accounts, take your cashiers check and walk into any local credit union. Explain to them your business (arbitrage) and that you need whatever volume of wires over whatever time frame... I'm sure they'll be able to set you up with the accounts you need.
And then change you and your wife's direct deposits, move your safe deposit box (if the new bank has any room!), change the mortgage payment, the car payment, all of your credit card auto-pays, the water bill, the garbage bill, the insurance bill, order new checks, deal with a new ATM pin.
