My argument for pricing is based on the USA. A large majority of homes are connected via overhead hookup and often do not require a transformer replacement since they are oversized a reasonable margin and have been for decades, it only usually requires fairly minimal work. Also, your price is in CAD not USD Also also, for the case that you already have power unless it was installed a long time ago its probably already in conduit and doesn't require any horizontal drilling
