In my opinion with 250 tt you should not be anywhere near a Jet with passengers on it. There is so much to learn about aviation that someone can learn from flight instructing for 500-600 Hrs, then taking the next step onto a turbo-prop/multi 135 job. Hurrying into it will not only make these candidates look bad in training and on line, but will also kill their confidence for later down the road because they never took the time to learn all the aspects of aviation prior to being a "professional pilot". It is a profession you have to earn, NOT BUY YOUR WAY INTO!!!!
