Making a guitar from scratch

Ok so theoretically if I wanted to make a fully hand made electric guitar (pickups and everything) how would I go about this.

I know fender use to have women hand make their pickups (some of those are highly sought after) and this is my main point of contention.

If I successfully made the body and pickups, how might I make a volume nob, pegs and maybe even some ideas on how to make actually good pickups.
