10 % would be sufficient just for quartering a deer and a ride to and from a stand. I just returned from an antelope hunt in CO. There were two of us with our guide. He was with us all day locating the antelope, took us to the hunting area and stayed with us throughout the hunt and gutted our animals after the kill and transported us to a butcher shop to butcher the animals. We hunted 2 days out of a 3 day hunt and each got an antelope. We tipped him $800,00 and we tipped the chef and his helper $300.00 for their part in making our hunting experience a good one. The tip is entirely up to you based on what services were provided.
