CrOn JOB

There is a file that is run each day to update subscriptions. I need it to send an email notification to the subscription owner and to the member each time a subscription is paid, canceled, or no funds available and to retry the subscription in 24 hours. At the next time the cron is run. Also need it to send an email when the member cancels the subscription and when the owner of the subscription no longer offers the service as a subscription product. Need to update the database when a member cancels a subscription, so the next cron run does not email them again. All of the email templates are stored in MySQL database budget is 30$
