I don't have any firsthand knowledge, but....
They cold-called me for some contract work a while back.
I asked my buddy who lives in Houston about them.

I never realized someone could actually swear more than me, but basically he didn't have one kind work to say and to run away as quickly as possible.
They've hit me up for more contract work since then, and I usually will ignore their messages or tell them that I'm not available.
