There are exceptions but you pretty much hit the nail on the head in that there are few other options. The only other one being to venture overseas..... OZ and Africa seem to be where most of the boys and girls go.
Word of caution re: C-Cat, everyone will offer to do the training for you but most will look after thier own and you might find yourself with a battle trying to get work out of whoever trained you...... result being an instructor rating with no job and still under supervision (worthless ticket). Unfortunate but true.
Steer clear of anyone offering to take your money for training and showing a reluctance to employ thier own product.
