A local arborist company who has a skilled climber on staff. I’ve done cat rescues on spurs before. 23m? Most bucket trucks have a 65’ reach if you can get a bucket truck to the base of the tree. Either scenario will likely be $225-255/hr for two men and a means of getting there and back to their shop. 

 That's more than the drone cost.  

 If you have a traditional bow and some microfilament line you might be able to run a larger cord up near it with that and shake it loose.
