I couldn't agree more with what retrotog said here:
"Expect to spend some money and time setting yourself up, spend lots of time establishing yourself as punctual, reliable and polite."
I know so many models that skipped this step, got frustrated that they didn't get many paid bookings right away, and quit. Think of it like setting up a business (with no guarantees the business will succeed) and go for it. Put in the initial hard work and your chances of success will be much higher. Expect everything straight away and you'll be disappointed.
Saying that, you have a great figure and you seem polite and able to take advice well, so I think you could do well!
