I know of at least one instructor in Kuala Lumpur, Malaysia, who can very likely help you with this. I went through intensive training with him and can say that it was well worth it for me. He's at Aikikai Malaysia HQ Dojo in KL(listed in the dojo database here, and there's a website); he's the shihan's son. I'll be glad to tell you more if you're interested; just drop me an e-mail.
I'm sure the other ASEAN folks will be chiming in...
