The only site I find is
http://www.bitcoincigs.com/. And I can't find any information on them. They don't have a facebook, and they are not on the bitcointalk forum. Except for the testimonials on their website they don't have any reviews from users that I can find googling. also their online testimonials are all in a span of two months from a year ago, then nothing.
It seems really unthrustworthy.
