Cell Bold And Font Size 12 And Highlight In Red

I am using this formula (Below) and it is working great. Only problem is that I want the client name to be be bold and font size 12, then I want it to highlight in Red. I also want the rows in colunm L to highlight in bright green.

Sub InputData()
Dim varUserInput As Variant
Dim LastRow As Integer

LastRow = Cells(Rows.Count, "G").End(xlUp).Row + 1

varUserInput = InputBox("Enter client name:", _
"Client Name", "")
If varUserInput = "" Then Exit Sub
Range("G" & LastRow).Value = varUserInput
Range("G" & LastRow + 20).Value = "Total".......................
