Wordpress: Looking for booking/reservation (SPA) theme



I am looking for a clean theme where people can browse different SPA’s and beauty salons and book their activities.
Important is that people can select a date and time (browse the agenda of the salon) and pay on the website.
An example is: https://www.treatwell.nl/en/

Any suggestions?
Thanks, Rob


No I am looking for an existing (premium) theme.
