You can contact Andy aka
atmccmn. He is also on this forum. He has a huge collection and he sells them as well. You also can check with Mohd Khairi, but have not seen him on the forum for a while now.
Besides that, you can just look around in nurseries around KL and Sg. Buloh. They do carry them sometimes.
I'm also a Till grower. Glad to know you're also interested in these plants.
