You are doing it right, run the wire in pvc and that keeps rocks from hurting the wire, from the ground freezing and thawing.Any quote I get is 2-3-5x the cost for anyone else because I’m a dentist.
To run wire to the barn I got a 7k quote then another quote from someone who knew I was a dentist and it was magically 20k for that one. Easier and significantly cheaper for me to do as much myself as possible.
Keeps the wife happy too.
She got a new car, it should be here within the next month.
