Come on guys...we've all had those instructors who couldn't care less about instructing and were just doing it to build time. You know them without even talking to them. They couldn't care less about you or how well you learn, as long as you're passing stage checks/progress checks/checkrides, they're content with you. Do we really want skiermws to be one of those? (Skier, you may think you wouldn't be, but if you don't want to instruct, you will be.)
Realistically there is very, very little on the job market between 250 and 500 hours. At 500, you can probably nab a entry level job (read: skydiving) to build you some time and get you towards your favorite bottom of the barrel regional or 135 job.
