Hopefully I can help out a little. What you're looking for is called "Variations" when setting up your services. For example we have a service named "nail art" When a client choose that service they are then presented with a list of all services that fall under that category that they can choose from. The times/duration of the service and price can be modified for each one. I'll leave a link below where you can check out step by step instructions 🙂
