One year verifications are EXTREMELY rare and not offered to to low-time pilots with just piston experience.
If you want a JAA licence PLEASE train at a JAA school. "Converting" licences is often a painful/expensive process.
I suggest doing your PPL in the UK, then seeing how you feel about dropping a further £50,000 on it as a career.
And remember... if you want to work as a helicopter pilot in any country, you need the correct licence, often flight experience, AND.... a work visa FOR THAT COUNTRY.
Please don't just google "helicopter schools" and then take a taxi to Gatwick, as an extraordinary number of people seem to do. Training as a helicopter pilot is not like taking a year off to travel around Australia. Do a LOT of research.
