Yeah,
Daedules (FTG) is a very good school, but getting a JOB with them as a full time CFI is not easy. They will most likely let you free-lance there till they get to know you. Call and ask for Sasha (chief pilot), he's pretty cool...
Flights INC (APA) the chief pilot is difficult to work with and they typically only hire internally... But they do APPEAR to have a lot of students. Call and ask for Mike Underreiner (chief pilot), you might get lucky
Aspen (APA) - Is an okay operation, they keep steady with there students, but it might be another tough gig the land a job.... Call and ask for Mike Shannon (chief pilot), he's an alright guy.....
Not too familiar with the schools at BJC..... To be honest man, there's been a 10% decrease in student pilots for the past couple years... Its pretty difficult right now to CFI in Denver. There is a lot of competition and not a lot of incoming students. If your not strapped down in college like I am, I'd recommend leaving state to go find a flying job.....
Hope this helps, good luck...
