Well if you need it for something coming up soon often you have to sacrifice quality. If you have the time I would suggest carving it out of wood. But this can be difficult and quite time consuming. In some ways it might be better just to buy it, even though it will be expensive, but that is up to you. You could cast the wand in resin, which is what the Noble Collection wands are made out of, but you'd have to make a mold of the wand.
