... so here ya go.
First, I think it was unwise to give a provider you know almost nothing about personal info such as name and workplace. My personal preference is to not give that kind of Info to any provider (instead use P411 and/or references), but I know some hobbyists are ok doing that. But giving it to a provider with no review history etc. is risky IMO.
As for the provider's lack of reviews, either she has a misunderstanding about how reviews work here, or she's trying to mislead you. Reviews don't disappear just because the authors aren't "high volume users." They stay unless they're removed due to not meeting TER guidelines (including being fake). Even if the author is no longer active or a member, or wants his/her ID erased, my understanding is the reviews stay (possibly with the user ID changed to some meaningless alphanumeric text).
If the verification site you mentioned is good enough for you, ok, but it's had some "issues" recently so I myself would not depend on it as the sole verification of the provider. And anyone can have a website and Twitter account. They tell you nothing about the provider's validity or quality of service.
If it were me, I'd pass. Lots of great, well-reviewed providers out there to choose from, and also on P411 which while not perfect I've found it very useful.
