Caretaking in Central/South America?

My husband and I would like to provide caretaking services in Central or South America. We can start in September 2007, but not sure what the best way of going about this is. Any advice?
By caretaking, we mean property management/house sitting/caring for someone's property and resources as requested. Often people have second homes that require on-site management, which is what we desire to do. For instance, in Costa Rica an individual's property can be taken over by squatters who also gain rights to the property. By hiring a couple to be on-site, they are assured of maintaining their property rights and avoiding long, costly law suits.

Caretaking ? what do you mean by that...take care of old people ? they got no dinero to pay you gringos...

I am original from Guatemala, That is central America and I am sure is a lot of volunteer job that is related of what you say about care taking services...Got to the web site of the country that you do want it to do it for you will find a lot of information in it and how to do it.

Your question is a bit vague. What exactly do you mean by care taking? Are you talking about working in a daycare, being a nanny, an orphanage, working with older folks? Please give more info.
