Pre-filtered calendar and booking process

Each of my service providers have ther own profile page which is a custom post type (this is separate from the author bio page that Appointments + uses).

On each service providers profile I would like to put a calendar and confirmation/checkout possibility for only that service provider. So the calendar has to be pre-filtered to show only that service provider.

If the provider offers more than one service i would also like to include the app_services, but have it pre-filtered to only show services for that service provider.

How can I do this?

Thank you
Theodor
