You must understand that I haven't been round a flying school for close to 20 years, so I may not be the best one to answer. I had 300 hrs when I finished my CPL and Instructor Rating, and I started teaching almost immediately. I was at a reasonably active school, and if you were willing to put in the time, you could put in 75 hrs a month or more pretty easily. It would be a good idea to be selective in your flight schools. Find a school that offers IFR and mulyi-engine training. From the start, tell the school that you'd like a job (for pay) pumping fuel and dispatching flights between flying lessons. A hard worker who shows interest is far more likely get ahead.
