N8n/Retell AI for Delivery Scheduling

We are seeking a no-code automation specialist to develop a system where AI contacts customers by phone to gather delivery information, including location and availability dates. You will set up Retell AI integrated with n8n to pull data from Google Sheets, make calls, and update the sheet after each call.

The solution must take into account the customer's time zone to ensure calls are made at appropriate times. The Retell AI configuration is already complete; your focus will be on the n8n configuration.
