Hello Dominique, 

Thanks for reaching out, we are glad to see you are interested in Amelia.

1) We don't have other live websites for Amelia, only the demo sites, which you saw. There is a customize section in Amelia with some styling options, and you can check out the options on the demo sites and in our documentation following this link. 

2) You can find everything you need to know about Amelia in our documentation following this link. Regarding Amelia and WooCommerce integration, there is the page that you mentioned in the documentation. We don't have any other documentation on that. Basically, you enable WooCommerce in Amelia-> Settings ->Payments and connect Amelia services with WooCommerce products in Amelia -> Services, when you create or edit a service when WooCommerce is enabled you will have the option in the tab Settings where you can choose which Woo product you want to connect to Amelia. You don't need to choose any, since one default Product is created when you connect Amelia and Woo, and in this case all services/events will be connected to that one product. And that is it. Customers choose and book a service/event in the Amelia booking form and after the booking process in Amelia they are taken to the WooCommerce Cart and Checkout page. 

If you have any further questions or concerns feel free to ask.
