Thanks for explaining that in an easy to follow way for everyone.
One thing though, I'd love to know where we could get a plastic mould for $1500 and an aluminium one for $10,000!
It's more like $25,000+ for just the plastic low volume one and $100,000+ for a high volume one, for aluminium I'd expect hundreds of thousands, but if you know somewhere which can do this for a lot less please let us know, it could save us some serious money.
