Automatically run vba if cell condition is met

[AawwYeahh]

Ok so I am currently working on a more user friendly template for invoicing. I have a data validation list to choose from multiple titles and have modified worksheet to act accordingly when "topic" is picked (IE invoice, Service, etc) my problem is I need different cells (all located in same space) with different formulas. I tried writing in formula to replace if condition is met but I lose cell formatting etc. I have recorded 3 macros but am wondering how to execute them without "pulling the trigger" of clicking on control button. And these are 3 separate macros, seem inelegant and messy. I am hoping someone has a better solution.
This is the default page layout (Macro 1)
Sub Macro1()
'
' Macro1 Macro
'

' Sheets('Layout") .Select
Range("A2:O11").Select
Selection.Copy
Sheets("INVOICE").Select
Range("A16:O25").Select
Selection.PasteSpecial Paste:=xlPasteAll, Operation:=xlNone, SkipBlanks:= _
False, Transpose:=False
End Sub

Macro 2 (for Service)
Sheets('Layout").Select
Range("B14:O23").Select
Selection.Copy
Sheets("INVOICE").Select
Range("A16:O25").Select
Selection.PasteSpecial Paste:=xlPasteAll, Operation:=xlNone, SkipBlanks:= _
False, Transpose:=False
Macro 3 (for construction)
Sheets('Layout").Select
Range("A26:O35").Select
Application.CutCopyMode = False
Selection.Copy
Sheets("INVOICE").Select
Range("A16:O25").Select
ActiveSheet.Paste
End Sub

Sub Protect()
Sheets("sheet1").Protect Password:="asdf"
End Sub

Sub Unprotect()
Sheets("sheet1").Unprotect Password:="asdf"
End Sub
