I’ve had good luck partnering up with other av companies to help each other out in situations like this.
You help them and they help you.
Personally i like it as it also can help if your slow and vice versa. You also get to experience how others may do something different than how you would have approached it and learn a better way.
Also look at commercial guys as this can provide a great learning experience as well.
When i lived up north i used to work with a commercial guy on a regular basis. It was my first experience with fiber. We linked two buildings at a forge together in the middle of winter that were thousands of feet apart. A very different environment to residential.
