I don't know who your talking about... but... I have a machine shop (don't make molds) LOL but the longest part of a custom mold is making the program. This person may be very busy with orders he has already been payed on. I have worms I need to copy that have been with me for almost a year, I can't put in front of people that I already have their money. I do think he should be answering your emails though... just the right thing to do.
