water shutoff valve with long stem to knob

I want to install a shutoff valve on the main water pipe under the house. I want to drill a hole in the floor over the valve. I want the valve stem to be long enough that it will extend up through the hole so that the knob will be above the floor. Then, I can turn the main water supply on and off from inside the house. I don't want a solenoid valve. I want a manually operated valve. I don't want a PVC valve. I want a brass valve.
