A few quick thoughts:
-Doing 8-10 dual review/proficiency flights at the Private Pilot, before you go all-in, can give you an idea of if it is for you.
-Keep your day job. Or maybe go part time.
-To be blunt, just make sure this isn't a phase or a "passing fancy" (lol) before you commit.
-When you go to a school, pay as you go. Don't give them a lump sump (unless a university program or the like), that can be bad if you decide it's not for you 10-20 hours in, but they have your money.
-Going to a 141 university program (or schools like ATP or CAE, though I've heard horrid reviews from a lot of people about places like those) has partnerships allowing you to get to regionals and some majors at 1000 hours.
-University Programs (if accredited, check on that) allow you to get an R-ATP at 1000 hours. They also train you up to the level you want, and hire you back as a CFI. Insurance and liability can also be better. Wherever you go, make sure they are insured and that you insure yourself. Don't risk it for the biscuit.
-Establish exactly what your goals are, then find a school that caters to those. Also find students/instructors/alumni from there and talk to them. Recruiters will tell you one thing, but reality may be entirely different.

Happy to answer other questions. Best of luck to you
