Create Template & Sell in Course?

Hi All! I help authors create and market their books. I have made about 10 different author websites in Squarespace, and now I want to turn one of those sites into a template that anyone can download and use for their own websites. I want the link to the template to be in the course I'm going to be selling. Is that possible?

Many folks here create plug ins for a Squarespace template and sell them.  They are not complete templates but they can make major changes to an existing template or template family and make it look unique.  So II say the answer is yes with conditions. You might want to explore this site as well:

You would need to manually create a duplicate of your template for each purchaser.
