From the video, either the PCB or the whole kit costs only 55000 indonesian rupiah, which is about US$3.87 If you can talk him into selling you the kit, it would be cheaper or less trouble to make your own.
But if you want to go the other way, here's what I've done so far. With a little more effort, you can make up the rest of the components or even the resistor values if you're patient enough.

Wooow Allen ! What a work Many thanks. I wrote him through whtsapp and waiting for him to reply. ( I have no hope honestly ) The cost you mentioned does not worth to talk about. I wish he sell.
