I gather that NAC will be back in business shortly, but see the thread on the USA forum for the latest info - or you could contact them and find out. Otherwise, check out the CAAs website, get a list of all the schools which are authorised to do the training, and contact all of them - then make your mind up!
As far as parting with your money is concerned, try to pay for everything on credit card. Then if it all falls through, you should be able to get your money back.
Have fun!
