I came across a few, but only 1 replied: "Breath & Health" (Yang style): http://www.breathandhealth.net/ I tried it and it was pretty good.
Others that I emailed, but did not reply:
(a) Master John Duval: (tried emailing but never received a reply, [email protected]) BUT, just came across this registration form and have just completed it (it's really long-winded though) - http://form.jotform.com/form/13394907302
(b) Chen Qiang, [email protected]
This is a new one, not seen this before:

If you hear anything let me know, or perhaps if there are enough of us we can ask the teacher to come to us to do classes?! I am in Springs (near JLT).
