I would setup the scheduler first: https://support.hostinger.com/en/articles/1583465-how-to-set-up-a-cron-job-at-hostinger
* * * * * cd /path-to-your-project && php artisan schedule:run >> /dev/null 2>&1
once that is setup, you can make a command and then run your command:
// Run hourly from 8 AM to 5 PM on weekdays...
$schedule->command('foo')
->weekdays()
->hourly()
->timezone('America/Chicago')
->between('8:00', '17:00');
