This has been a good discussion about various business models and methods. But I don't understand why a couple participants need to say no one can survive in business without doing it their way, all the time addressing several of us who have been in business successfully for many years. Summarizing all the comments I think that all of us in this discussion, who have been successful, have one thing in common, and it is not pricing. It's because we sell ourselves i.e. our expertise and our integrity.
