Tiered Pricing for Services Based on Booking Frequency

Allow service providers to set up tiered pricing for services (e.g., dog walks) where the cost per service unit decreases based on the weekly booking frequency. For example, 1-2 bookings per week cost CHF45 each, while 3-5 bookings per week cost CHF40 each. This feature would enable more flexible pricing strategies and incentivize frequent bookings.
