Warren,
Sounds like fun. Your basic needs really depend on the market you will be going into. I came over here to Japan to consult for LC 7 years ago, and I was not prepared for the tuna, corn, and mayo pizzas they were pumping out over here.
I also had no idea that Christmas Day was the #1 pizza day in the country. The first one I worked, we started the day with double the usual daily sales in pre-paid orders, and just got busier from there.
You also have to think about toppings and if the place you plan on setting up has a beef import ban, as that will affect pepperoni, sausage, and other meat toppings.
Cheese is also a hard thing to source in many places. The US subsidies milk prices, which only really happens one or two weeks a year, but that allows other countries to slap a tariff on US cheese, so IQF from New Zealand is far cheaper in many non-US markets. Interestingly enough, when I showed the tariff information to the US consulate here they denied that the US subsidizes milk or that there was a tariff. That goes a long way toward showing you how useless consular employees can be.
Give me a PM if you have any specific questions.
