There's no such thing as "lap sawn" lumber. There are lap joints, but I don't know why you'd use one on a neck unless he's trying to avoid a scarf joint to the headstock, which is entirely possible but would be unusual on a Fender-style neck since that design doesn't require any joint at all.
I don't see anything about the instruments to command such a price, either. He's using the least expensive woods he can and still end up with a playable instrument. The hardware is uninspiring at best, and I'll call that bridge a POS although anything is better than the Rube Goldberg vibrato unit Fender uses on that design. He admits the body is a glue-up, which isn't the end of the world but it's not premium no matter how many adjectives you use to describe it.
I suspect they're very well-built instruments, but American labor is über-expensive so attention to detail is pretty dear. I know if I built and finished a guitar from scratch, it would have to be in the $3K range or it wouldn't be worth my time, and my time isn't terribly expensive these days. If he's trying to make a living doing nothing but this, then even at that price he'd have to make and sell about 30+ of those a year to make a decent wage. It's doable if he makes them in batches, but I wonder if there's that much market, especially considering he's not the only one doing it.
