You're over standard weight. This is what Part 119 says about weights:

Crew—for each crewmember required by the Federal Aviation Regulations—
(A) For male flight crewmembers—180 pounds.
(B) For female flight crewmembers—140 pounds.
(C) For male flight attendants—180 pounds.
(D) For female flight attendants—130 pounds.
(E) For flight attendants not identified by gender—140 pounds.

As for how to finance this gig, let me tell you that flight training is expensive. And how expensive depends on how much kool-aid you drink from the marketing department of the flight school or flight instructor that is trying to sell you. I've heard people getting through CFI with $30k while I spent over $101K and didn't get any instructor ratings. So the spectrum is broad. Your options to learn how to fly to becoming a professional pilot working for a fractional, charter, or air transport is also broad. I would seriously do research on what is the best route for you. It could be as simple as going to a local airport and sign up with a flight school there to buying your own airplane and train in it and then sell it when you're ready to move on to twins, etc.

My final word of caution or advice as you call it, is to do a LOT of research. Talk to a lot of people, and read a lot of threads in this forum for information. You'll eventually get a good feel for how this game is played. Just don't play it until you see the good, the bad, and what I've seen, the real UGLY.

Good luck and welcome to aviation!
