Is this lender legitimate? Something seems off

[Nicole Heasley Beitenman]

Hi BP!

I'm looking for a hard money lender for a 6-unit apartment complex. My agent gave me the name of a lender she found on BP, Joshua H. Brown. She warned me that she did not know him and had never worked with him before, so this wasn't necessarily a recommendation, just a potential option to check out. His account is closed on BP. He seems to have VERY little criteria for lending. He answers my questions with very little detail, requiring me to really dig for answers. I asked him if he could somehow verify his legitimacy through references or other means, and he said he could e-mail me some references along with his business license. Is that enough? What else should I ask from him? I'm trying to find other lenders, but I'm having a tough time doing so. 

TIA!
