If cron doesn't work, you should probably specify the command like this: /opt/php/5.6/bin/php -q /var/www/hosting username/data/www/your domain/periodic/cron.php this is how I registered the command on my hosting, everything works fine.
There is no paid level on this list (but you may make Premium like wanted). You need to create a new one via Studio->Permission App and then make it paid via Paid levels App. And the work with this new level in Visibility filter.
