Hello, @whiskeyworks .
Thanks for reaching out and posting this question!
Since you’re using a Shopify-supported theme, then replacing the Add-to-cart button and removing the sold-out badge may be something that our Theme Support team can help you with. While we’re unable to provide account-specific support via the Shopify Community, we’d be happy to assist you with a customization request through live chats. Simply visit the Shopify Help Center and log into your account to create a support request. However, if our Theme Support team determines that a customization falls outside the scope of the Shopify Design Policy, then you can consider hiring a developer to assist you with customizing your theme. Should you need help finding a developer for your store, then you can take a look at our directory of certified developers on Shopify Partners.
If you have any other questions on this topic, then don’t hesitate to let us know!
