If you can fly when ever you want, also meaning that you can pay what ever
it takes, you could realistically knock out your PPL and your Instrument
rating in 6-8 months. I'm sure others will say it can be done faster and
they'd be correct, but starting with 0 time you need to give yourself enough
time to actually learn and build experience. Multi-engine can be done in a
long weekend for under $1500. From there you can go to one of the
specialized type rating schools for the Lear work, however they may require
a minimum number of hours before you qualify to enroll.

My question would be who's Lear will you fly? With minimal hours in type,
you won't be able to rent one. If you buy your own, you will have problems
finding insurance. Best case scenario... you are independently very wealthy
and you can just buy a Lear and not worry about insurance. And you can also
afford the BEST training and you'll make recurrent training your top
priority.

Be careful. Do some self examination and understand your motivation. It can
be done, but learn how to do it safely and correctly. Do not let your need
for speed surpass your capabilities.

Thurman Munson, the Yankee catcher, had 516 hours TOTAL flight time, 33
total hours in Citations, and had owned 4 different airplanes during the 18
months that he was a pilot. Too much money. Too much airplane. Too much
speed. Too little experience. Touch and goes in a jet. The last one he
didn't use his checklist. First forgot to lower his gear, then he forgot to
lower his flaps. Way behind the power curve, too slow on final with the
flaps up, they sank into the trees. 516 hours TT 18 months more money
than experience.

Please be careful.
