Automatically create a copy of Master sheet when data entered into specific rows

Hello all,

I am wondering if it is possible to automatically create a copy of the "Master Do Not Delete" sheet when data is entered in rows A4-80 on "Staff" sheet? The newly created sheet should be automatically named the same as the data entered into the previous mentioned rows. And I think it would be good for "Master Do Not Delete" to be a hidden sheet so no one can delete it accidentally.

So to give an example of what I'm thinking:

"Mike" is entered into Staff!A4. When this is entered, Excel automatically copies Master Do Not Delete! and renames it "Mike" and places this newly created sheet at the end of all sheets.

I hope this makes sense.
