House-Sitting in Costa Rica - Finding Opportunities...

Any suggestions on how to find house-sitting opportunities in Costa Rica? I realize that there are a lot of Americans with second homes in Costa Rica that only live there part-time. I thought it would be mutually beneficial to find a house-sitting opportunity.

My husband and I have lots of past hotel experience (maintenance, housekeeping, and front desk) that make us ideal candidates for house-sitting.

Let me know if you have any ideas on how to do this... thank you!
