The key with this guy is simple, if you read closely, in order to get the mold price stated you have to send him a cad file otherwise you will have to pay him an additional $35/per hour to design your jig for you, which at that point he will create a cad file based on your design. Then he will use his cad file to machine the molds and create cutting tool paths. I have been designing and drawing on cad for 25+ years. This day and age almost everything is done on cad. Maybe 5% is still hand drawn. So this mold veture depending on how complex the design is can cost you well over $500-$600. The $35 design rate is in proportion to todays current labor costs. I do freelance cad design and I have designed some molds, it is very time consuming as you are always making a one of custom mold for someone. If I were like Do-It and sold molds well the cost would be offset by the volume of molds I sold. In Do-It's case they sell 100's. Naturally like anything else there are other guys out there that will charge less.
