I think the author underestimates consumer-grade video-cutting software. He may have lost a weekend of work due to an iMovie UI bug, but not everyone has.
Hire an architect to do the specification ($40k for 2 months), and one board designer ($120k as contractor for 6 months) and two layout engineers ($36k total) to implement the design. For redesign, use a contractor at $75 per hour (budget $4k). This is for top-quality Valley talent. If you do this overseas, costs will be 1/3 but you will need more redesign.
$10k for software tool licenses
$50k for prototype PCBs
