I have one of those jobs all i need is a internet connection and I'm good to go. The pay is so low it really would be a waste of time to work, but if you have a decent steady income from outside the country it's the place to be. Antigua is a little more expensive because of the tourism and large community of expats and retirees, but on the good side that means more services available. Many good restaurants, and some decent shopping that caters to foreigners. Also because the city creates a lot of revenue for the country the Central Government does a fairly good job of keeping it safe, though the National Police are not only not any help, they are to be avoided. The darker the uniform the more corrupt they are. As for moving here, from what i hear is easy, but what I and most people I know do is stay here for 3 months on a tourist visa then make a weekend trip to Mexico. Can do that indefinitely, besides I only plan on staying in Guatemala for a year or so, until i am fluent in Spanish, then I plan to ride down to Colombia. Well to Panama, then a boat, there is no road connecting Panama with Colombia.
