If i try to do this myself what are the chances of messing up my car? I have never done something so involved.

Well I will put this like this. if your not comfortable with this. Then let someone do this for you. I would suggest calling around for good reviews with a shop and getting some estimates. Here is another option you can call the dealer for their auto body shop and ask them to do this it will also save you some money and you will have a great warranty on it. It should save you about 35% on labor rate. Then ask for a discount.
