I agree - get them to finish the body & neck, then it's not much more than an assembly job. YMMV but I certainly don't have the skill to apply a finish - it's not as easy as just slapping on some paint & hanging it to dry :) Nor have I ever stoned or crowned frets - fortunately they had been so well installed that neither of my necks needed it.
FWIW, here's the "plan" I followed to make my second one:
align tuners, drill guideholes, install tuners
install LSR nut with shims
install trem claw
wire pickguard
thread ground, output ground & output wires through holes, place pickguard on body & tape down
wire ground & output jack (tape down jackplate)
test output (with a tuning fork)
attach neck, check alignment, bolt on
insert trem posts, put trem on (with body protection), install trem springs
put strings on, tune to B, check action, alignment, adjust trussrod
align pickguard, tape down in place, drill holes, screw down
align jackplate, drill holes, screw down
align trem cover, drill holes, screw down
install strap buttons
leave overnight, adjust truss rod again if necessary, tune to Eb
leave overnight, adjust truss rod again if necessary, complete setup (intonation, action height etc)
enjoy :)
I won't pretend that it's as nice a guitar as having an expert custom build one, but with some work I've been able to make it play very nicely. At least it's made of top quality components so it sounds good & stays in tune well which is what really matters IMO...
