[solved] a few questions for an Efb

So I am working on influential/rich efb and I was wondering are blood banks for vampires alllowed and if it is well written could ancestor of my pureblood once started a school for training of vampire hunters the school would be closed now of course.

Vampires in the HP universe are not the friendly, live with mortals normally type of vampires.  A blood bank for vampires does not really fit in the universe, and the rarity of them would not really afford a rich/influential lifestyle.  Let me know if you have any questions.
