There's a FB group for people looking to hire drone pilots and some of the members have equipment to help people find lost pets. I don't know if anybody on the island has a drone with this capability and are also members of the group, but I do know that a lot of people will travel for a job. Some will even do the work for free if the location is somewhere exotic (like Hawaii) in exchange for getting their travel expenses paid. Getting a drone with this capability is on my bucket list, but I'm not there yet.
