Doesn't make sense for a GB.
What this really is is a basic directory wordpress theme bundled with a bunch of training for people who like to have their hands held.
This isn't a new idea; it's a tried and true method:
1. Set up a directory site, using a nice looking Wordpress Directory theme (lots here for free)
2. Add business listings
3. Reach out to the businesses asking them to verify their listing info is correct
4. Monetize the site:
a) sell premium listings
b) sell ads on the site
c) sell digital marketing services to businesses who need them
With a GB, you might be able to share the training videos and marketing materials, but the Wordpress theme isn't licensed for resale, and that is the heart of this system. You don't want to build a business by sharing an unlicensed theme that you won't be able to update or get support for.
Just my 2 cents.
