Dear Vanchai,
I would like to clarify that the present version of software can't be enhance with Thai language. We are finding a workaround to this.
I am also not aware that we need 5 units for pilot. We are also awaiting pricing approval the the new price after our discussion the other day. Therefore we need the new price point approval before we place orders.
As for other items you've mentioned below, I will discuss this with management before responding to you after this Eid Mubarrak break.
Thanks.
