Im not a CFI but i can tell you some info about my school.

Location: KTMB (Tamiami Airport. Miami, FL)
School: ADF Airways www.adfairways.net
Pay: $20/hr
Cost of Living: Miami is not cheap!
QOL: I could say Average. The owner is a woman, she is Colombian. You can fly a lot if you choose to. They have an agreement with Miami Dade College so they get students from there too.They will not BUST YOUR BUTT. They are somehow flexible with you.. (schedules). Lots of Colombian students, some of them are pretty good looking . The Chief Pilot is a great guy. He is a Captain for Eagle. This is probably not the best school of florida, but its ok. Most of the instructors from here go to ExpressJet.

You could also check another school named "Dean International". It is also located at KTMB and I heard they pay a little bit more.. i'd say about 26$ an hour. I think its the biggest school of the airport, they have probably 5 times more airplanes than ADF Airways. However every time I hear on the news a small airplane crashed in Miami... it is one of them. Maybe its because they have about 60% of the aircrafts from KTMB, but who knows... just keep that in mind. Their Owner is from India. So their main business is people who come from there.

Hope this helps!
