With no prior flying experience, you're looking to spend around $70K to get your CFI, CFII and optionally your MEI ratings (that's the most practical way to build time and receive a little income for it). There are other options, but instructing is generally at the top of the list. All this is true until your 1500 hrs, after which is the big walk through the regionals.
Bottomline - you're settled with family, have a job - it's a little too late to pursue a career in flying I would say.
On the other side - you can still achieve your dream of flying. Just get the PPL. Fly with your family from time-to-time. The best gift/memory they'll ever have.
