WhatsApp Bot for Google Maps Integration

I need a WhatsApp bot that can help my drivers locate sites by sending them Google Maps links based on site names or numbers they input into the chat. This bot will help improve the efficiency of our operations significantly.

Core Functionality:
- Drivers will input site names or numbers into the chat.
- The bot will retrieve and send back the corresponding Google Maps location link.
- Admins will have the ability to add, update, delete, and audit changes to site names/numbers and their associated Google Maps links.

Admin Control:
Admins should have full control over the site names and Google Maps links. This includes the ability to add, update, delete, and audit changes.

Security:
For admin access, basic password authentication will be sufficient.

Additional Features:
The bot should have a scheduled backup of data to ensure we don't lose crucial information.

Ideal Skills:
- Proficiency in bot development, particularly for WhatsApp.
- Familiarity with Google Maps API.
- Experience in implementing basic security measures for admin access.

Experience:
Freelancers with a track record of developing similar bots, particularly for logistical purposes, will be prioritized. Please include relevant samples of your work in your proposal.
