Put together a list of differences between what you are putting together and what is on the website in question. Make the list detailed as possible, things that are obvious to you are clearly not so obvious to them. E-mail the list in a polite manner to inform the client of the differences, and that yes, if they want to drop any of these features it will simplify and speed up the development process. Then they can decide if the extra features justify the extra time.
