Thermostat housing on 2002 Chrysler PT Cruiser

My repairman quoted $1000 for thermostat replacement and thermostat housing.
There is no coolant in coolant box and it's low in the radiator. Plus the water pump is leaking and it needs all new engine mounts.
Is this a rip off?

The water pump alone is a 6 hour job and after adding the engine mounts and thermostat it sounds about right
