If you are looking for free setup - you can combine ACF plugin with Custom Post Types to create your products/services (or extend woocommerce products) and for forms use a Forminator (in free version it provides date-range field needed to select dates). You will need also some plugin for calendar sync. Source: about 1 year ago

Gravity Forms, WP Forms and Formidable Forms are all paid form builders. You can do this for free with Forminator. Here's a link to their documentation to guide you through stuff: https://wpmudev.com/docs/wpmu-dev-plugins/forminator/. Source: about 1 year ago

WordPress won't do your requested features out of the box, but plugins will enable you to do what you're asking for. I recommend the Forminator plugin which supports your needs:. Source: over 1 year ago

Gravity Forms is a very reliable premium form plugin. If you can buy, you can go with it directly. If you want a free form plugin you can go with WPForms. But its Pro version is quite costly, so you might not want it if you will eventually buy the pro version.

You're most likely looking for Advanced Custom Fields (here is the PRO version), Carbon Fields, CMB2, or any other custom field manager. Source: almost 2 years ago

If you don't wanna pay for ACF Pro but still need Repeater Fields, I recommend Carbon Fields. It lives entirely in your code (there's no "Create Field Group" GUI like with ACF) but it does it's job very well. Source: over 2 years ago
