How to start in commodities trading, specifically soft goods.

Hello, I have a BS in Ag. Bus. and have spent the past 10 years working in a variety of agricultural segments.

I am interested in transistioning into commodities trading, and have a real interest in soft goods.

I realize this is a Chicago based industry and I am in San Francisco, but what is the best way to break into the business?

What is the best way to get started?

Thanks,
HRS
