Ah. Yes that's about right for a panel swap. Upgrading the service conductors is what costs $$$.

You also have situations like my friend - his current 100 amp service is arial, but if he wants to upgrade to 200 amp service he will have to pay for buried line.

Amusingly enough you can add a separate 100 amp service arial if you convert to a duplex even if just on paper ...
