PHASA has a link of the associated/accredited PH schools located throughout South Africa:
PH Schools
Many have web pages and lay out the information required to participate.
Many schools will allow you to attend, you do not need a study permit for these very short courses (under 2 weeks). When the proposed "longer version" comes to fruition you may need one to stay for 6 months to study.
By the way, from what I understand before you can get your license you will need experience on top of the course!!!
Most courses are under $2500 CDN
The books required (at least the list suggested to me) were about $400 shipping included, as you can not get them in N.A.
You will have to fly over obviously, so there is another $2500 to $3000
The biggest hurdle you will have is the residency issue. Need to citizen of RSA or what we call in Canada a landed immigrant.
If you have at least $250,000 CDN dollars equivalent to invest in RSA you should be able to meet the grade and emigrate.
As Enysse says it is a tough job. Any of the PH's and business owners on this site can attest to that fact.
It is a lifestyle not a job, so if you really want it. Go for it!
Good luck.
