No update, but unless you have previous, successful, history with the company I would need to ask why you might think they have approached your organisation and not another agency they have used before?
I’m not personally suggesting that DEEP SEA KISH Co. based in IRAN are a bad company to do business with as I have no direct experience with them, but I have seen other companies in the past, known as are bad to do business with, jump from agency to agency and choose some of the smaller ones to try it on with.
