Tim and James, Thanks for elaborating on my two points. Sometimes I am a man of too few words.
Jim, You are very highly successful in your business. Why are you so worried about the schmuck who might underbid you? You've got a reputation.
Sell yourself and your company not prices.
By the way, you were involved in a similar discussion in March of 2011 and you had several posters saying the same things that have been said here.
