You may already know one. You can get those made, and cheaply, if you know where to go. Most vampires are just not that conspicuous. Before you get all excited and either run for the garlic and stakes or start looking for someone to bite you, let's take a little reality break. Let's look at things rationally.
Vampires are neither demons to be destroyed, nor deities to be worshipped.
They didn't die and mystically come back as nocturnal ubermensch to some cursed half-life, despised by God and shunned by the decent. The whole idea is ludicrous. The vampire is not physically superior to your everyday human. There are some subtle and less than subtle differences, but overall, there is no reason to spend your time and energy trying to find a way to become one. God does not hate vampires.
