Hello

In order to add the buy button you require a shop management extension to do that, as such a button will integrate with payment system. You can use third party store for that. We unfortunately do not provide customization support, sorry. https://www.joomshaper.com/joomla-templates/category/ecommerce You can kindly take a look at the ecommerce templates here, it will be helpful. Please do let me know if you have more questions.

is Templates & Page Builder-Personal for Helix not enough to make this button?

Yes of course, you can use our ecommerce templates made with helix utlimate framework too. With the templates plan you have access to all our templates.
