I am writing a book/novel thing and there is this family. They are hunters, that have been after vampires for centuries. They have their own buisness and research labs pacifically used to find ways to annilate these creatures. Problem is, i don't know what to call the buisness. I want something simple, that doesn't give away what they are, that someone would just walk past the building and not give two thoughts about it.
A bit like Torchwood in Doctor Who (Sorry for the bad example lol)
Something similar.

Thanks for your help and sorry for such a weird question lol
