"First, I don't think that Vietnam is anywhere near close."
I could not disagree more. If you have been keeping up with the information provided by the company, Vietnam needed a Bio safety Certificate which was supposed to be handed in within a 30 to 60 day period. The company is never going to tell you that the paperwork was handed in. I have other things I could say, but I will not. You are wrong on this issue, I believe.
This idea that the company cannot mass produce is a huge fallacy. It spreads like fake news. It is total horse dust. If the company were unable to mass produce, they would not be concerned about getting financing there to build a silk plant, nor would they have spent three years, as you say, trying to get into Vietnam. I mean, honestly, enough nonsense.
"even if they can produce large quantities of product, there have been no reported deals made with ANY company that wants to buy their product."
You and I are never going to hear a word about any deals/contracts until the company is mass producing in Vietnam and have been for a while. Then, and only then, will the company reveal any contracts, and reveal they will.
"I am about to cut my losses if nothing happens within the next few weeks."
Again, a sign of youthful impatience, IMHO. You would be selling at absolutely the wrong time. However, that decision can be yours alone, so good luck. JMHO
