Took three years to do all my training up to CFII/200 hours, started work the week after finishing and within fifteen months had 1000 hours, mostly instructing. During the three years of training I never did a rating/license/hour building in the same place and built as many contacts as I could, one of them kept there word and took me on.
Cheers TS
ps. hate the 300 hour thing for FI in Europe, FAA rocks...
