You cannot 'register as a training facility' in the USA. All training leading to the issue of a JAA licence or rating, conducted outside the JAA, must be approved and may be completed only within an approved training organisation. It is not possible, BritishGuy, to freelance in the way that you suggest.
And before we rush off at a tangent, organisations such as UKFT that misleadingly advertise a 'JAA compliant' PPL are not approved as they are merely giving instruction for an FAA certificate and not a JAA PPL.
