I sent Pearl.com an email asking them (out of curiosity) how they managed to provide engineering in various states without licenses.
The response I got back was:
[blue]Thank you for contacting Pearl.com
I apologize for any inconvenience.
All of our Professionals go through a rigorous screening process. We use a leading third party verification service to confirm every Professional’s listed licenses, certifications, education, and/or employment history to make sure they have the expertise required for the category they are seeking admission to. In addition, Professionals must pass an exam to demonstrate mastery in their subject area before they are accepted onto our site.
Furthermore, answers of Professionals on the Site are provided by Professionals and are to be used by Customers for general information purposes only, not as a substitute for in-person evaluation or specific professional (medical, legal, veterinary, tax, financial, etc.) advice.
In addition, when asking a question on Pearl.com, the customer sets the amount that they are willing to pay to speak with a professional. The payment is collected once a professional responds to the question. 100% satisfaction is guaranteed so if the customer does not get the help they need, they may request a refund of their payment.
An overview of this process can be found on our How It Works page:
Please let me know if you need further assistance and I would be happy to help.[/blue]
This looks like a general automatic response email. I'm thinking of replying back to push the subject a little further. They are pretty tight with their anonymity.
