I found a local certified installer here:
Where to Buy VentureShield. Hopefully the link will still have the right box checked; PM me if it doesn't. I would think someone would be near you in Pa. If not, come visit us & have it done here - they said it would take about 2 hours, we can entertain you for that long!
I'm sure there are other good brands out there but this is the one we were most comfortable with. They quoted us $625 for the standard package (basically front end + tops & sides of the side view mirrors), + another $50 if we wanted the headlights done. You can also have it custom applied to other areas. The package cost was less than what I expected from my research; not cheap but cheaper than a paint job. Wish I'd gotten it on my daily driver, which looks new except for the front which is machine gunned with rock chips.
For the adventurous you can also order the kit & install it yourself. Even if a pro installs it you can probably spot it on the car IF you know where to look - but I'd rather have that than chips etc.
