Does anyone here have some reasonable statistics or experience about how accurate an automatic online quoting system for a typical essay website is? Let's say, there's a form to fill out some fields and script automatically calculates how much to pay for the order. But the problem is that essay requirements are unique and it is not always possible for a script to provide an accurate quote.

For example, a student may only require 2 pages, but it would take reading three books and doing a poll to research and write those 2 pages. The script would calculate a total price as $50, but no writer would be willing to do so much job for, let's say, $30. I understand such orders are not taken by writers and the client is stuck. Does it often happen?
