Where's the HVAC guys ....?

I need to install a propane furnace at my camp. I think 50,000 BTUs will get the job done but I'm not sure? It's less than 1000 square feet, 4 rooms, 8 shitty windows with an insulated attic, am I in the ball park? Where hell can I buy one? I'm sure Johnson Supply has something but I lost that privilege as my friend is no longer a Steamfitter. Also is there anything tricky I need to know about a propane furnace?

i think 50k btu would do pretty good.. plus propane is clean as is gets, i have a propane back up in my garage and its a 100k btu, it does not get the job done but it will kill the chill if i need it to and my shop is 3600 square feet with 12' ceilings..
