INNflight: CFIs should instruct for the pure love of instructing! They obviously love flying, so that should be sufficient. Besides, if an instructor requires an absurd request like money/payment for their services they should be laughed at in their face and then you should go find some instructor that will do the job for free! They want the hours, right? Why give them hours and money. C'mon! They should do the job for free in order to get a feel for what their airline job will be like.
