Making that kind of money as a cfi will take serious dedication, and sales work on your part. Meaning you will need diligent time management skills to always have something to do with your students even when the weather is bad. Also needed are good sales skills as you will need to pick up a ton of business. The first year I wokd as a CFI I made 11,000 this year right at 12,000. Doubling those figures would be a miracle.
