My install required new service to our detached garage. The electricians charged ~$3k to install the new service and the charger. The electric company is coming soon to energize the service (install the meter, etc.) and that'll cost ~$180. I probably could have found an electrician to do it for closer to $2k, but they were good and installed upper-end Leviton breakers/panel, used beefier cable, etc.
