Android App - Retreive Email and sound Alert To Manage Resturant ONLINE Orders.

I need an android app that retrieves email from a POP3 server, given the username/password... and sounds a LOUD AUDIBLE ALARM when a new email is received and continues to sound the alarm every 10 seconds until the user acknowledges the email. EVEN if the device is in sleep mode!! Once the user acknowledges the email... An ALERT should be send out via SMTP (server, username, and password need to be configurable) to a GROUP (configurable) of emails that the email has been received. The Audible Alarm will STOP... but the email will remain in the INBOX. The User should then have the ability to DELETE the email. The app must work even if the tablet is in sleep mode. There should be an option for how often to check the POP3 account. The practical application is a Restaurant Delivery Service. We use a 3rd party to accept our Orders Online. When they get an order, they send that order to an email address. We want to mount a Kindle Fire on the wall in our restaurant with this APP on it that would receive the orders and ALERT the staff that an order is available. Once we have acknowledged the order -- the audible alarm needs to stop. Once we deliver the order we need the ability to delete the email from the inbox. Again... App must work on Kindle Fire or any Android Enabled device.
