Automatic Visa Interview Rescheduling System

I'm in need of a system that automates the rescheduling of American visa interview appointments. Here are the project requirements:
- Monitor the website https://ais.usvisa-info.com/es-ec/niv for available dates
- Automatically reschedule when a date becomes available
- This system should be developed as an extension
- I am open to the system being programmed in any language
Ideal skills needed would include web scraping, automation, and proficiency in JavaScript, Python, or Java. Familiarity with the visa appointment scheduling website is preferred but not a requirement. Any interested freelancers should have experience in creating similar appointment scheduling systems.
