Hang on a moment, I never suggested anybody should quit because they are not a professional. And erecting a large structural frame with a crane is not quite the same as cutting grass. And what about if you love what you do AND get paid for doing it. OK I put a few caveats in to cover my ass because certain activities within framing are very dangerous. But this was not meant to discourage, only that inexperienced people should seek professional advice.Remember framing can be great fun but safety must always come first.

Good luck with your build, I hope it goes well.
