I know that I've not heard of them...
and after a quick visit to the Internet Movie Database, I was unable to discover them on the site.
However,
This does not in any way mean that they're a scam... it's very possible that they are a small upsatart agency.
Best advice to give you is to just research everything about them... if you can't find enough to convince you it's legit... then it probably isnt.
Good luck.
