Kent,
I hate to tell you this, but you choose a bad business to get into now. The market is flooded with competition, both from domestic and foreign mold makers, aluminum prices are on the rise and over all demand for molds is way down from where it was even 2 years ago.
I've been in this business for over 20 years and I have never seen it as bad as it now.
I wish you good luck and I would like to suggest that you have a back up line of work to fall on to pay your bills.
