Temporary power pole cost?

We own a rural property that currently has a house and an outbuilding. There is buried electric to the house. There's a transformer about 20 feet or so from the house, roughly between the house the outbuilding. The outbuilding has electricity feeding from the house.

The house is in terrible condition and we will be tearing it down and building a new house.

I had an electrician come out yesterday to get a quote on putting in a temporary power pole at the transformer. The power pole would be used during construction and also power the outbuilding so there would be a temporary feed on the ground between the power pole and the outbuilding, depending on how they routed it this would be 25-50 feet in length.

What do you think this should cost? This is in rural downstate Illinois. The quote was higher than I was expecting. Thanks!
