This is a really great discussion. I am coming to this conversation as a client (owner-builder) who is a bit overwhelmed by the whole process. I have been in contact with a couple TF'ers who want to sign me up for a lot of design work. By a lot, I was told anywhere from 80-100 hours of design work. I may start another thread (with more specifics) out of respect for the original poster but I wanted to express my gratitude for the information here.
