How about: Have one big button for Quick Start, like you do, and either adding some buttons for "Wedding Quick Start", "Company" etc below that button.

Or on the page you land on after hitting "Start Now" keep your editable page, but also add those more specific buttons at the top (and also one with "Nah, leave me alone." to get rid of them).

You can also get rid of the "Start Now" button and just allow people to get started on the front page. (Have your invariable welcome section at the top, but put the edit area below. And of course you will need a good idea for how to get the URL of the newly created temporary page to your users.)
