Script to check for daily backup file and email is none exist

Need a script I can schedule daily to verify that a backup file exists on the local machine. If it doesn't exist then it needs to use blat or some similar solution to email a notification about the missing backup file. The location of the backup will be C:\VTBackups\ and the filename structure is VtDb_VT_YYYYMMDD_21_00_00.Bak, so the backup for today would have been VtDb_VT_20180828_21_00_00.Bak.

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
