Several decent brands that aren't super expensive.

If DIY: You can probably do your hood with a 5' x 5' piece, or pay more for a precut piece, but may not allow for edge wrapping.
$150-$200 for the piece.
More expensive brands could be $250-$300, depending on your source. But they typically don't sell pieces. You'd have to find a provider that would sell you less than a roll.
Pro: The prices can vary widely. You'll just have to do the work and make some calls to get info and quotes.
I've found around 1000 but it is a quote with hood and bumper. Didn't get one for just hood. I assume the hood might be cheap since it is one pretty straight forward piece.
