What should I do?? My business name is "Inside & Out Const." and last year I saw a yard sign that said "Inside Out" something. It was very relative to my business. Now when I registered my name 6 years ago, there was nothing even close to mine. I don't even know if this guy is a registered DBA. What should I do about this?? I would hate for this guy to do shotty work and then as the name gets passed it affects me or my great quality somehow gets his phone ringing.
