Availability checking program

Job ID: 32931582

Budget: $30 – $250 USD

I need a program written that would check the availability calendar of two different websites every 5-10 minutes, 24x7, and notify my via text message if a slot becomes available.
The two websites are:
https://www.recreation.gov/permits/234622
https://www.recreation.gov/permits/234623

I would need to be able to set the date parameters (i.e. June 9th - Aug 27), and have it check for any boxes in the calendar that change to an "A", and then notify me. However, if it were just checking June, July, and Aug. calendars that would be fine.

Ideally program would be hosted on GoDaddy (where my website & email are hosted). If not, could be a program that runs on my Mac.
