I prefer to have just a few pages where the client can scroll down to see different sections. Can the pages be reconfigured to my needs in this way?

Yes, you will be able to add sections to any pages that you'd like or adjust sections as needed. You'll have the ability to duplicate particular sections within pages if you want to copy over any formatting or create a new section from scratch. The tutorial videos included with your purchase will walk you through all of these options.
