Ray, it's the best $108 you will ever spend. $100 for the service and $8 for 100K worth of search and rescue insurance.
Considering the size of the group and lack of any help or cell service for 100 miles. Just charge everyone a extra $10 on the trip to offset the cost.

Anything can happen out there, rattlers will still be active, there was one in our campsite on the last trip.

Anyways your welcome to mine but I have to get it to you.
