Thanks Direk
We are doing our best in streaming communications between partners and the company. The sales and marketing training is the start.
As in your case, please note that the quotation was a year ago and under normal business practice without any VAD system implemented, a quotation usually lasts from 30 - 60 days with exceptional arrangement to 90 days.
I'll await update from K. Pramote to see how further I can help, especially how solid you think the order and when it can come if an appropriate price can be given.
FYI, I was informed last Friday that our factory in Italy will be moved summer and we couldn't produce anything in August. Therefore, please forecast and stock up preparing for that.
Best regards 
Kenneth
