I'm on my way through. I already have a university degree, and am still working full time outside of aviation. I did PPL then CPL, consecutively, but at the same school. Immediately started my instructor rating, but after three weeks of no flying because of weather I started my multi-IR. I will add float and whatever else I can afford and seem to need to get that first job.
It is fairly typical of people who go the instructing route to do instructor first, because then they can do ME and IR on the school's planes, at an employee discount.
People who head for the bush may get their first summer job with just CPL, then come back in the winter to get more ratings.
Remember that the IR has to be kept up with annual renewals and currency requirements.
I think the professional pilot schools are more appropriate for someone who wants a degree as well as flight training, and/or needs the discipline of a structured school program to keep moving through the system.
