I like the "Official" certificate better than the Gomez one, although it looks like he may have some Japanese language on there, which would be a plus.  
Reminded me of the old, annoying "Hare Krishna" days at the airport (anyone could go to the gates in those days), in Waikiki, and even downtown.  Drums and cymbals.  And to some extent the t-shirt and bottled water vendors (with a mandatory message) at Hanauma Bay. 
The Kingdom of Hawaii advocates are missing out in my opinion, by not issuing and aggressively marketing citizenship papers, marriage licenses, drivers licenses, gun permits, business permits, marijuana licenses, etc.  Who could stop them?
Can "official" state employees, selling "official" certificates, compete with motivated entrepreneurs?  I would be surprised if they could.  Not without "muscle".
