In LATAM a combination between TV and social media is definetily the key. You can be aggresive and even get a top figure in the media to promote your bussines. Identify what is the key population target for product, once you have done that you can find a top figure that is loved among your target population. Start doing campaings with that figure, a combination of social media and TV campaing will definetily be a a good one. I would start first with the TV presence (which is the more expensive) and then continue with social media.

Find somenthing that you would want in your home country but you can't get at the moment, or not at least at a reasonable price or good quality. You can become expert in a field and provide that extra and get a profit. For example you can start resealing merchant for a niche that you like, eventually you will become good at spotting what the market needs.
