Quick Question,  Provider has 2 different TER profiles,  one with 2 great reviews, the other stating bait and switch.  Different phone numbers same email.  After some digging seems the bad reviewed phone number is that of an agency.  

Id like to think provider is real and now independent.  

2 questions...

A. Can these comments be faked by the providers themselves?
B. Any advice on pre-screening for an outcall,  is it polite to request some more proof in an email

Here's a cool tool by the way, takes an image and searches the web for same images,  already discovered a few asian providers were fakes using this.

2 profiles, vastly different, wow, that's a tough one.  To answer your questions, A. I'm not sure what comments you are referring to, and B. doing an outcall with this lady is not a good idea, IMHO.  The fact that you would 'like to think provider is real...' is worthless.  What you think doesn't matter, what is actually true does.

With the large number of verifiable quality providers available, I would just move on if I were you.

It might be that she has gone indy...  but I'd not see her at this point.  If you are a newbie, there's just no reason to see a less than well reviewed provider.  
What I would do is circle back later on...  she might have more reviews & you'll have more experience.  Even then I'd go in cautiously as in all TOFTT circumstances.
