substitue

I live in rural Central America and the local people really enjoy the Americano baked goods I make. In most recipes, I found I can substitute AP, but am afraid to try others as I have no access to bread flour. Does anyone know of a viable substitute that would not include a 12 hour ride on a chicken bus to the next country over (If they even have it). Thanks and Feliz Navidad y Feliz Año Nuevo from the third hut from the river just past the palm trees.
