How it differs from setting up the page
Setting up the Facebook page gets the page going once, with basic content. The content package then adds new posts, images and videos. They are two separate add-ons; if you have no Facebook page yet, you need the set-up first.
With Premium
With Premium, Facebook content is included every month; you do not need to ask for it separately.
Where to ask for it
In the quote form among the add-ons, or in the portal as a new feature; it also shows up as a suggestion on the About step.
Let us look at your site.
The quote form takes two minutes: package, add-ons, your company details. You see the price at once, and it commits you to nothing.
