Where can I buy cheap Phal seed sowing medium?

[terminator]

I am a newbie. My boss loves orchid but she wants me to take care her orchid. Hehehe, she wants a terminator (fishman, who knows nothing about orchid) to "take care" her plants. Anyway I have to do it otherwise I will sleep in my car.
Luckyly, I got some pods/capsules which will ready to sow next months. Do you know where to buy cheap seed sowing medium? How to trade seed? Thanks Terminator.
Some pictures of my pod:
