From a logistics standpoint, what does it take, time and money-wise, to get yourself set up in a place like Costa Rica?

For example, a lot of people in the U.S. telecommute nowadays. If you have the kind of job where all you need is a fast and stable internet connection, but you can do it from anywhere, what's it take to get yourself relocated, buy a >1000 square foot abode somewhere with 99% reliable power, internet, climate control, maybe set up a home gym in your extra room, and start living your life as an ex-pat?
