Alerts based on conditions

I want to set up alerts to specific users for this scenario.

There is a column called Termination Date which is the date the user has been terminated. From that Termination Date, the admins must disable the user from a application and input the date once the user has been officially disabled - that column is called Application Disabled Date.

The admin must disable the user within a 10 day window from the Termination Date, so if the Application Disabled Date is blank after 8 days of the Termination Date, i want Smartsheet to shoot off an alert and everyday until the 10th day as long as the Application Disabled Date is blank. Once a date is inputted in the 10 Day window, there will be no alerts. Can someone please assist?
