Are you referring to a buried electric fence? If so you must consider that a dog not wearing the collar or a child or intruder, all can come into your yard, so from a liability aspect, it is not the best solution.
Also a friend lost 2 akitas during a cold winter when they had a heavy coat and there was a fair bit of snow on the ground, they just didn’t feel the shock.
Just a few things to consider.
Can’t help you on the price, check with a fencing contractor would be the best bet.
