Not sure if this would help, but I recently hired a contractor who specializes in running underground lines for utilities.
Especially needed when going under roadways, etc. They call that procedure horizontal boring.
For this job, I didn't need to go that far mostly needed them to go under a publc roadway - and needed to use a method approved by the city here.
The minimum charge was $1,500, so that was our cost. They use a boring cable to drill the hole and then pull the plastic tubing through. It was a 2" line for us, because I wanted to use a 1" pvc line inside, which I did. They brought the tubing right up to where I did my connection - within' 1 foot. Except for the digging where the tube went in and came out nothing above ground was disturbed. They did all the locates too. Pretty slick!
