I know this isn't the hemisphere you had in mind, but I did recently see an ad from Maldivian Air Taxi looking for FO's. I can't recall which site, but it was just a few days ago, and if i recall, the minimums for FO seats aren't that high. It might be a place to build some time and get a foot in the door (but probably not particularly beneficial to married life!). The Maldive/Twin Otter scene used to have a Kenn Borek connection, but I don't have any direct knowledge, perhaps someone else out there has the inside story.
