We aren't doing much of that since our operators have retired and I am not up to "training" some bozo that "always wanted to run one of those things", but I will tell you this: You better stay busy and careful because liability insurance is HIGH. We never had a claim, were always extra careful, but there is a lot of underground stuff out there. Some of the phone lines can cost you 1 to 5 Million $ in down comunications time for one day if you damage them. We have one of these lines running through our farm. Work is pretty easy to get even though there is not near as much of it as there was in the 90's. Then there is the chasing the contractors round and round to get paid.
