Wand question

One thing I want to know is this:  If a wizard or witch has their wand
broken (as happened to Hagrid) what's preventing him from getting a
replacement somewhere?  Even if Ollivander's been warned not to sell to this
person, does this prevent trying Gregorivech (the guy who sold Krum his
wand) or whoever supplies the students at Beauxbatons?  Or, for that matter,
making one him/herself?  How difficult are wands to make, anyway?  From the
description, the most difficult part would be getting hold of the "heart" of
the wand---the magical substance at its core, be that dragon heartstrings,
veela hairs, phoenix feathers, unicorn tail hairs, or whatever, but I would
bet that a good alchemical supplier might have any or all of these things on
hand.  ISTR a place on Diagon Alley that would probably carry the whole
lot...it was where Hagrid and Harry bought potion supplies for him when he
first went there.

Another source for a wand might be a hand-me-down, a la Ron in the first two
books.  Would Hagrid have been able to use his father's wand?  What _does_
happen to a wizard's wand when he dies?  Hagrid's "old dad" died before
Hagrid was expelled from Hogwarts, and since Fridwulfa was no longer on the
scene, wouldn't that have made Hagrid his heir?  Or does Hagrid have
siblings or half-siblings we haven't met yet?  _That_ would make things very
interesting indeed...having Hagrid dealing with half-siblings that don't
even want him in the family.  Maybe that's why he stayed on at Hogwarts?
