Add text and signature to email script

Hi I have an email script i use every week to send a few cells of data to different clients from an excel spreadsheet. the script i use converts the range of cells to html opens an email and pastes the data in. I would like to add text in to the body of the email as well saying " Hi Please find the weekly hours below". I also need the script to keep my corporate email signature.
I have attached the script below. I have visited many forums and have seen that this can be done but i have strugled to make it function. My working script is below, if someone could asses the script and add in the relevant information i would be so happy.


Sub NGARDA_WEEKLY_HOURS()

Dim rng As Range
Dim OutApp As Object
Dim OutMail As Object

Set rng = Nothing
On Error Resume Next
Set rng = Sheets("Hire EOM Hours").Range("G8:H18").SpecialCells(xlCellTypeVisible)
On Error GoTo 0

If rng Is Nothing Then
MsgBox "The selection is not a range or the sheet is protected" & _
vbNewLine & "please correct and try again.", vbOKOnly
Exit Sub
End If

With Application
.EnableEvents = False
.ScreenUpdating = False
End With

Set OutApp = CreateObject("Outlook.Application")
Set OutMail = OutApp.CreateItem(0)

On Error Resume Next
With OutMail
.To = Sheets("Hire EOM Hours").Range("T16")
.CC = Sheets("Hire EOM Hours").Range("T17")
.BCC = ""
.Subject = Sheets("Hire EOM Hours").Range("T1")
.HTMLBody = RangetoHTML(rng)
.Display
End With
On Error GoTo 0

With Application
.EnableEvents = True
.ScreenUpdating = True
End With

Set OutMail = Nothing
Set OutApp = Nothing
End Sub
