get a cheap press like this: 20 Ton Shop Press. You can get a 20% off coupon from almost any magazine these days. Then you can use angle iron, structural steel shapes, etc. welded together to make your dies. It won't be perfect but you can do a decent job if you make yourself some decent tooling. There are some manufacturing type companies that have chunks of broken press brake tooling you might be able to get for next to nothing. My neighbor stocked up on some nice tooling from a company who makes elevators.
