Freediving course on West coast of Thailand in November

[rachhasescaped]

I am planning to travel the West coast of Thailand in November. I am already a Dive Master and plan to do lots of scuba diving, but I am really interested in doing a free diving course as well. Can anyone recommend any places/shops on the West coast that do good free diving courses?

I heard some shop in Koh Lanta have free diving course.
