How does one get into trading equities or commodities for a brokerage house?

After much thought, I have decided that this is what I would like to do. I'm not afraid to make a commitment and work hard for this. I self educated myself on this topic and have had a successful track record trading mostly energy and tech stocks. However, taking the plunge into a new career is a bit overwhelming. Does anyone have any idea of where to begin? I appreciate any and all input.
