I agree with everything IR says, especially this:Have you considered the approach many companies take, which is to provide a table of average costs, along with a note to 'contact us for more details'? That way, customers have some idea what to expect, at least if they want a system similar to something you've done before. Have a form that users can fill out, describing the essential features, requested (but not essential) features, time frame, etc, along with their email address. When they submit it, you can review it and get back to them. It seems the most reasonable solution.
