HELP ! QUiNCE MASTER OF CEREMONY SPEECH !

Hi my name is Lynette. I am 2O years old and very out going, confident and well mannered. I guess because of these traits my cousin who is turning 15 THiS SATURDAY ( MAY 3 ) wants me to be her MC ! I have spoken in front of large groups so I am not scared. Its more WHAT DO I SAY ! Does any one have a broken down speech ?? From the greeting to the ending ?! PLEASE HELP ME I DONT WANT TO LOOK DUMB !

Thanks for all your help !
