Easy question. Try something harder.
Yes you can get any film that you need. Yes you can get slides developed. No hassle.
Kodak, Fuji both have large presences here. You can drop off your film at a Nacional Supermarket and they will do the rest..

MaineGirl: I saw your comment about having film shipped here. No, that is not the way to do it.
Most of us use a private mail forwarder-currently, I am using Business Mail, which is ok +/_. You start an account with them, they give you a number and an address in Miami and you have all your small stuff sent there. They get it for you and you pay them a small fee per pound and any customs duties incurred. They usually avoid the normal customs fees, so it comes out a lot better than you going to the Customs house and banging heads with the burocrats there.
This would be the way for you to get your film, if you are not happy with what is available here...
