Sorry for my language but I use a translator.

I'm thinking of putting a template and I have a question. According to this record:

"Free" templates are released under the Creative Commons Attribution 3.0 license .. This means it can be That used for private and commercial purposes, edited freely or redistributed as long as you keep the link back to asdesigning.com. If you would like to remove the link, you should buy an Asda Commercial License. "

I ask to be sure. Is if I add a template for the free license, someone can use it for their customers (if he creates websites for them), provided leaving my link to the page in the footer?
So he creates websites (using my template) to clients and he gets paid for it. The condition is to leave a link?
