Then tell the client to give you a budget simliar to pricegrabber, bizrate,
AOL shopping and you'll get started on hiring a development team. ;o)

that has one available for you to use. In addition, there'd likely be a
significant amount of screen scraping that will have to be done.

There's a whole lot of 'it depends' involved with that question.

> And can a site like this be done in Dreamweaver?

DW is text editor. You can build pretty much anything provided you know the
particular programming language you want to use to handle it all.
