@Steve Babiak, unless he registered with Pennsylvania as a contractor, he would not show up on there, the company as the OP stated is from NJ where he would be registered. he should be registered in PA if he is doing work there, so i agree, he should have shown up on those sites, i am a contractor in NJ but do not do work in PA, not even my own properties, so i do not show up on those sites.
