Automatically Re-name Sheet To Cell Value & Create Copy Of Hidden Sheet

I have a workbook with a hidden sheet ("Template") and a visible sheet("New Job"). I need code so when cell F1 in "New Job" is populated:

1-the sheet is renamed to the value of F1,
2-a new tab is made (a carbon copy of the hidden sheet "Template")
3-the new tab is named "New Tab" and marked as unhidden.

Public Sub Worksheet_Change(ByVal Target As Range)
ActiveSheet.Name = Range("F1").Value
End Sub

Function WorksheetExists(SheetName As String, _
Optional WhichBook As Workbook) As Boolean
Dim WB As Workbook
Set WB = IIf(WhichBook Is Nothing, ThisWorkbook, WhichBook)
On Error Resume Next
WorksheetExists = CBool(Len(WB.Worksheets(SheetName).Name) > 0)
End Function..................
