Where can one find gas furnace prices?

What is the reason for a furnace to go through all the systems of operations and the ignitor sparks but no gas?
Typically, it is going to be the gas valve. The system sends a 24 volt signal to the gas valve and it opens. I you are getting 24 vols to the gas valve and no gas, it will be the valve.
How do you convert a furnace to propane or natural gas?
Change out the gas flow orifice size to propane and adjust the gas valve.
Why is it necessary to have a pilot safety shutoff on a gas furnace?

Perhaps the pilot light is out and the gas has been turned off at the valve.
Main burner on furnace burns all the time even with thermostat turned down a no electric signal to valve from thermostst?
Depends on what type of furnace you have but it sounds like 1.a wire from the thermostat is shorted, 2.the thermostat is stuck itself or 3. the main gas valve is stuck. Try turning the power off to the furnace next disconnect the wires leading to the gas valve if this stops it check 1 and two if this doesnt stop it then it is number 3

How do you know if the thermo coupling on your gas furnace is bad?
The thermocouple tells the gas valve to supply gas to the burners. If the thermocouple is bad then the furnace will not work or the pilot will not stay lit. A properly working one will have a reading of at least 12 milliamps.
How does the gas safety valve work on a home forced air furnace?
The gas valve is an electrically powered device that is wired at the end of a series circuit so that it can only be energized (open) if all of the safety switches upstream in the circuit are closed and the pilot flame is lit on a standing pilot furnace.
