Teacher couple looking for international housing and work in education for 1 year.

My husband and I have requested a one-year leave of absence from our teaching positions in Colorado and are looking to live internationally for a year with our 2 daughters, ages 8 & 12 so they can experience language and cultural immersion. We are looking for experiences in Southeast Asia, Central or South America, but we are open-minded about any international opportunity that presents itself!
We are seeking house/pet sitting opportunities as well as work, preferably in education, but we would do a variety of other jobs, depending on the situation. Ideally, our daughters would either attend a school where we teach or we would homeschool them on our travels. Matt and I have each been teaching for 19 years – he is secondary Social Studies and I have taught elementary through middle school as well as Deaf and Hard of Hearing students. We have both taught internationally, in Honduras, for 3 years and we speak fluent Spanish.
