class for learning to make bio diesel

I plan on building my own processor in a coupleof months, and have =
dabbled a little in making bio diesel with the blinder already. I have =
thought that there might be some classes that I could attend.  I have =
found one at the U of I in Moscow Idaho, but they charge a 1,000. =
dollers for the class.
I live near Boise Idaho, and I was wondering if you knew of any class =
that I could attend withen a couple hundred miles that was not too =
expensive.

Thanks, John Harris
