Vetting a 1031 company- Anyone ever use Discount 1031 exchange?

[Justin Summers]

I'm doing a 1031 and am planning to use Brian Greene with discount1031exchange.com but started to think how do I even know if this is a real business.. The attorney Brian Greene seems to check out but how do I know that "Brian Greene" is actually who I'm talking to and not just someone that setup a website using his name & Credentials?  Just wondering how I should check out and do due diligence on a 1031 exchange QI Before wiring them $500k from my closing.

Thanks for any input.
