The procedure is in the Offer. But I want to explain to you again. Like I said I trust you so I am offering you very special conditions. I hope you will be a good and reliable business partner.
You are not paying anything until I bring the Gold to Dubai, you / your buyer receives the consignment, refine it to 99.95%, sell it to your end buyer and pay me.
To secure and make me use my own money to send the gold to Dubai, I need security through SBLC which will be in the Bank (just in case something goes wrong with the payment).
