I am not an expert -- I'll leave that to our moderators -- but I do love Latin America, so I'll hazard a few opinions/things to think about:

Of the countries you list, only Suriname is in South America; does that matter to you? (I don't think it should, unless proximity to SA is important to you for some other reason -- e.g., you have a vacation home in Patagonia.)

I've not done any research on travel costs, but I'm betting you could find cheaper places to get in and out of. Of course, this depends on where your HQ is; if you're in Miami, then the trips to and from Jamaica will be cheap. But if you're flying from Europe or the Far East, you won't get a direct into any of the countries you mention.

I would add Panama to the list. I've only been there twice, but the infrastructure is the best in Central America, there are decent inducements for business, and there's plenty of willing labor. Plus, they have a significant international presence: All the big banks, plus Intel, many others. Here's a pretty good info site: http://www.businesspanama.com/

As with all such decisions, I'd look for "references" in the form of other pioneers: I.e., find a company (competitor or peer) who has set up a DP center in Latin America, and follow them -- or at least find out more. If they're large enough, it could be that they've pre-trained the labor force for you.
