That's the thing. We'd have to find out and you'd need partners you can trust in those other regions. It's not one-man show.

You would need a centralized website to buy the products such as Shopify. You would need 3PL. That are in the three regions you wanted to be in but also could deliver to countries outside of those three regions. The reason forcentralization of the website is so that if you wanted to buy items from multiple vendors or stores at the same time it could drive additional cost downward
good thinking.
