No problem! I'm glad your so interested in the world. So for your questions:

Yes that's first bits a great idea. We can say it takes between an hour and a week, even a month in the rare individual to completely turn. 

The US is the country I'm most familiar with and many others I'm sure, so your right on that front as well. 

I'ma be blunt here, they Rob the vampires they kill, sometimes scam or even steal from normal people. The base is funded by Hawkes parents. 

Vampire's eyes get redder, and their skin paler, they tend to be colder/ have a harder time sustaining body heat, and of course they murder and eat people. It's a guessing game mostly, there can be accidents sometimes where normal people are wrongly killed. 

Once again, no problem I love questions.
