Mike,
Fine, market the higher end people, but by publishing your prices you remove the need for them to call you because you've already told them what they want to know. We deal with a lot of high end customers and they are just as price sensitive, if not more so than the lower end, so if they think your prices are high they will look elsewhere and because you answered the price question on your website, you lost the opportunity to to explain what they get for their money.
Not your best idea IMO.
