If it's not tied to the Bujinkan, Genbukan, Jinenkan, or Toshindo organizations then IT IS FAKE! Most of those organizations do not even call themselves Ninjutsu anymore, prefering Taijutsu instead. There are a lot of people out there who use the Ninja term to gain students and all they are really teaching is some karate mixed with tae kwon do and judo.
EDIT: I just googled them and I can tell you straight out they are fake and don't waste your money. Definitely playing on the Ninja image to get people to give them money, probably overpriced too. First off If they spell it Ninjitsu and not ninjutsu run (some people say it's interchangable, but it's not.. ask anyone who can actually speak Japanese). Second, it's an organization under Ronald Duncan, who if you google has been found out to be a fraud as much as Ashida Kim. Save that money and invest it into real martial arts dojo/shibu. I pay less for an entire year of training than what you would pay for a month. If you want some more info, hit me up, my e-mail is on my profile page.
