Website: Gmail, mapping, and Calendly integration

We have a customer signup forms on our websites that verifies the customer addresses with a third-party mapping API (towercoverage.com). If the customer is within our service area, we want to send the customer an email with a Calendly link to schedule the service installation. If the customer is outside our service area, we want to notify the customer with an email that we are unable to provide service.

The existing websites are written in Laravel and hosted on Namecheap. We worked unsuccessfully with another Upwork developer to develop this automation. Unfortunately, after months of development, the project is incomplete. We are happy with the front end forms but unhappy with the broken automation. We would prefer to fix and finalize the existing sites but are open to an entire rewrite.

This is a one-time project with the potential for ongoing development work.
