The only plus I can see with that site (theservice 4guide.com)is the fact that the service is free. Their “strict standards” don’t seem all that strict to me, almost on par with saying “do you have a heartbeat?” They are telling you to just trust them, but their revenues come from the businesses.

They say they turn down more companies than they accept. If you believe that, I’ve got a bridge in Brooklyn you might be interested in. On the other hand, they could be a referral service created or financed by some of the businesses themselves to steer business their way, so they may turn down their competition. A lot of referral services work that way, unfortunately. I wouldn’t expect much from them, but you never know I guess. Good luck.
