Since you are not near service you should try a couple of simple steps.
With furnace in the off position!
Open the outside panel and look over the furnace. Look for wasp nests, debris, in or around the burner. After gently cleaning around the pilot light and burner get some computer type canned air blast and dust the exterior. Put the little straw up the pilot light tube and give it a couple of squirts. Watch for dust, spiders or webs, etc. coming out.
Then have someone retry the start sequence and watch. Does the pilot light? If it does but won't stay lit they it could be the thermocouple. It may be possible to bend the thermocouple a fraction of an inch closer to the flame to get it to stay on.
Do some research on the search function above. There are other problems like the electronic board, sail switch ( it detects that the fan is working so the furnace won't overheat), slightly low LP supply pressure, thermostat failure, etc.
Ask around, someone might loan you a little electric heater or know where to buy one nearby if you have AC.
