I ran my own when I built the farm, renting the huge, drive on Ditch Witch machine, but Valley Drilling does run water/power out to fields.
I also used Hinkle & sons for running the main power from the box to the barn, I have no idea of the number is still good, but I talked to Billy Hinkle at 571-641-6705
I have no idea what your terrain/fencing situation is, but call a couple, have them come out and give you estimates, compare the estimates, what is included/not included, check references, schedule work with contractor of choice.
Make sure you specify frost-free hydrants, NOT made in China (the best ones are Made in USA still). Installed with a proper French drain system at the drain hole/base, with a geo-textile type filter above the gravel to keep it from getting clogged with soil.
It never hurts to state the obvious when doing any construction project.
