Usually people do not deal directly to FXLQ but to one of their IBs because FXLQ doesn't really have a real customer service (they never answered my mails for instance).
There are several IBs. I uses one (FastBrokers) but there are others. The minimum deposit for my Broker is $500.

FYI, some people don't want to deal with FXLQ because of its link with Robert Gray.
