You have a big problem Bonnie Lad. What do you know about farming in these other countries? How can you advise farmers if you have not either farmed there yourself or at least trained there as an Agronomist for several years.
I am not suggesting that you are not well trained, perhaps very knowledgeable, and a real asset to farmers where your expertise was acquired, but having farmed in four countries in both hemispheres I can tell you that the whole culture, requirements, problems, stocking rates, seeding rates, insect and animal pests, and a myriad of other things are so different under different climatic circumstances that I doubt anyone would give you a starting post.
I do not like being negative, and provided you are willing to start from scratch again (possibly even re-qualifying - I took a degree by distance learning in Oz) then I suggest you go for it. Have a positive attitude, believe in your own ability but be prepared for set-backs, work hard yet find time for enjoyment, be kind to those who depend on you and hopefully, like me, you will be able to say "I am pleased I tried, even if sometimes I failed." Those who do not try things other people think are impossible never have the real joy of success. When we moved to Portugal six years ago someone tried to put me off by saying I was tto old at 60. Balderdash. I wish you well.
