Ollie needs help

A few days ago Ollie got hit with his second porcupine in the week. He came back with quills all around his face and inside his mouth as well as a lesion resembling a bite mark. I pulled the quills out and cleaned the wound (having done this with Lovah before) and thought it would be good. As the days have gone on the wound has gotten worse and I feel my only option is to get him to the vet. I'm afraid of the wound becoming infected and/or there still may be quills in his face causing a bigger issue. Of course I want prepared for something this extreme and could really use some help. 

Please and thank you.
