It's a fine line...I want the business but I don't want to waste time with people who don't want to do business in a way I think is realistic.
I met with some people recently who wanted direct response copy and I gave them a quote and they wanted to move forward but when I repeated the price and the terms I was pretty much told to get lost. I wasted about three hours meeting with them and sending a lot of emails back and forth.
My mistake: not pre-qualifying the prospect. This happens all the time but it was still painful--my fault entirely.
