I think you and Ormsby should get in touch and start speaking about starting this guild. I think you can quite confidently contact Galeazzo Frudua, he's not on this board and I don't know him personally but he seems the kind of guy that is nice, proud of his work/service and that doesn't like people to get scammed. Dylan Humphries from Daemoness is another dead serious guy about his working ethics and would accept a guild imho. You know, you need a little snowball to start an avalanche. Eventually seeing people accepting some work ethics and making it a "branded standard" will force people to join the guild and comply. But...maybe it would be interesting to open a thread here and ask people who wouldn't feel at ease to buy a custom luthiery guitar, how they would feel if there was some kind of guild endorsing working ethics to protect the customer.
