With all due respect FootiePJ, I think Leviebaby88's bad experience was with someone who contacted him under the pretense of wanting to be his exclusive Mommy, this person was not a professional AB Mommy or Caregiver. Leviebaby88 you can correct me on that if I am wrong.
Professionals with testimonials and positive reviews like the people at ABDL Nursery Texas are from all accounts, very loving dedicated people, they just happen to approach Caregiving for AB's as a business and there's nothing wrong with that, they fulfill the needs and fantasies of many lonely AB's who have the disposable income to splurge on that type of an experience. Legitimate nurseries like the one in the link you provided are far from the catfishers or scammers that Leviebaby88 dealt with.
That being said, I'll reiterate, whether it's a girlfriend you are introducing to your AB side or a Mommy you meet online, professional or otherwise, there is always going to be a little bit of mistrust until you get to know the person.
FootiePJ, I wish you luck in finding a caregiver or a sitter that can give you the care you require
