Tbh i don't like do anything through PM, it's seems a bit suspicious
Some dubious people always hide under the pm to hideth their fraudulent activities. Op should explain everything here if he is really can do what he claims to do. I believe to start an exchange involved a lot of security and marketing and op is already with neg trust on his account and that is a clear sign that people or traders funds can easily get hack by op himself after opening the exchange for you.
