Well in that case, knock yourself out. No labor involved other than your own is a good, solid deal.
You do plan on doing a complete cover right? Door jams, etc? If so, it may not hurt to buy a little extra just so you have the exact color match down the road if you ever need to do a repair or add a painted mod.
EDIT: This was in response to you comment "I am kind of thinking something like this. Labor would be me "
