Nice video
Sorry don't mean to step on your thread or take away from what you did here...
....however some of the labor and cost can be mitigated by buying used (holes already drilled...maybe even an already loaded) or buying from a place like the Stratosphere
Guitar Parts, Bodies, Necks, Pickups, Fender, Gibson and more | The STRATosphere
I have managed to build quite a few nice basses for far less than what they would cost new by buying used Bodies and Necks (some of which were already loaded) it takes a lot of time to search for parts but if you want to do it on the cheap it's worth it...in the long run

The P/J bass seen here I put together from random parts sourced from all over the internet...all used...Craigslist, reverb, Talk Bass, and all together i have less than $450.00 into all of it
I started doing this four years ago....on my birthday every year I build a bass made with random parts and after playing it for a few months I then donate it to a less fortunate player, or raffle it off and donate the money to a worthy cause
everything on the bass is Fender/Squier except the tuners (Schaller) and bridge (Omega)...
