Add me to the list of those thinking the prices for the molds on that site are cheap. When you add the cost of the material and the overhead it would be very hard to beat them. I’m thinking the work is being done outside the states.
If I was to start from scratch to do this work, I would buy a used 3 axis Bridgeport type CNC mill. You should be able to find one in decent shape for $10-12K; if you take care of it you will get that money back when you’re done with it. Middle of the road Cam software should be from $2-4k. You can figure a few months to learn how to use this stuff, if you get skilled instruction. I’m sure you can get by with less but the end product will suffer.
