When I worked on ultimatecoupons.com, we wanted users to leave within a few seconds, because they clicked affiliate links. Maybe they got the info they needed in 10 seconds?
Having been a freelance web designer myself, I can say that in my experience, people don't just click and buy web design services. If you are selling pre-made websites, your prices better compete with the cheap WordPress template sites (<$50). If users see a higher price, they'll bail. If you are selling something custom, users will bail when they don't see a phone number or when they see you aren't local to them (they want to meet you in person to discuss the details).
