starting exporting business, need advice

So I live in Canada and recently I've come across an oppurtunity to export a pretty unique product to the markets of other countries. North American and European exporting and distributing rights are already taken, but the rest of the world is pretty wide open as far as this product is concerned.

Just wondering if anyone has any experience with a business like this or has any recommendations on relevant reading material on how to start and maintain an exporting business? (preferably but not necessarily in Canada)

awesome, thanks for the book recommendation
