Base metals from mines - Brokerage customary fees

Hello everybody,

I have just registered to t2W and my main purpose was getting a preliminary idea about the following:

It seems that an owner of several base metals mines is willing to supply to me ores directly from the source.

Together with a partner who has contacts with potential customers, the thought is to act as brokers;

I need to learn the basics of being a broker in this field, customary fees, etc.

It would be very much appreciated if you could refer me to good material on that,

Thanks in advance!
