Impressive metal work...most of us can only dream of being able to accompish what you do. Most of us are just hobbyist and you raise the bar.
Personally I am amazed at what I have been willing to attempt on my car just because I see someone like your shop making it happen first.
Ignore any of those negative comments/PMs. It's just the crab mentallity....when one gets a leg up the others just want to grab him and pull him back down into the pot. Or as our mothers said " if you don't have anything nice to say just don't say anything at all".
