We were thinking about propane heaters, but we aren't sure how well they need ventilated, and on cold winter nights, that could be a problem. Plus, you continually need to purchase propane, where as with a wood burner, we can just walk outside and cut down a tree is needed.

I don't know the exact cost of the building because my grandparents are paying for it, but I believe the building itself is around ~3300. Then there is thecost of a wood burner, insulation, foundation supplies (lumber, concrete), rocks, accessories, etc. So I'm going to guess the grand total will be around 5000. Not too bad if you think about it. Many, many years of memories will more than cover the cost.
