To fly an N registered aircraft in the U.S. for hire you need a US FAA CPL. You already have a foreign CPL so you can fly your foreign aircraft in the U.S for hire while exercising the privileges of your foreign CPL.
This addresses licensing issues only. Flying a foreign registered aircraft for hire in the U.S. may require permission from another federal agency, but I am not positive.
I hope this helps but your question may require clarification, i.e. what are you really asking?
