Hi,
Thanks for the interest in our plugins.
If you are using WooCommerce already you would want to purchase WooCommerce Tickets:
https://theeventscalendar.com/product/wordpress-wootickets/
We do not directly show the available tickets left, however, you can add that information, Barry has some coding to do it in this post:
Tickets Remaining
And you can follow our themer’s guide to move and edit the template in your theme:

Let me know if you have any follow up questions.
Thanks
