I wish you good luck!
For future introduction i recommend you rather importing seeds, at least some species, because seeds is less work, much cheaper and you will have higher success. Some plants you can keep as seedlings, because they won't take too many years to fruit and the fruit quality will be ok (ross zapote, caimito, jaboticaba, etc). But you could later also import budwood and use your seedlings as rootstock.
Other plants which are difficult to graft, or the scions are very perishable, i would also suggest to import the whole grafted plant (mamey, sapodilla, etc.). From my experience, I think regarding mamey and sapodilla maybe 1 of 12 scions imported from US did make it. If i had the chance i would have rather imported the plants.
