Advice: Physio Assistant requirements?

Would you tell me what would be required to get me up to the level required to apply for Physio Assistant jobs?

I'm 42 years old and currently broke in Cambodia, teaching english (TESOL). I have trained as a sport and remedial massage practitioner with London School of Sport Massage and for a few months in the UK had my own part time business as a massager and reflexologist (trained and registered with AOR). I also have a BA, majoring in Education.

I would love to become a Physio but it is out of the question that I try to fund myself for a further 4 years study at this point in time (and soon I'll be too old ???).

Apologies for my lack of knowledge, but would it be possible to be a Physio assistant with my qualifications? If not, what would I need to do in order to be able to apply for positions?

Any comments at all that you would like to make are appreciated.

Oh, and I'm not bothered too much about what country... UK, Greece, NZ, Oz.
