I have seen a portable metal wood burning oven,pretty big for portability, it gets really hot inside. The pizza that he made "looked" pretty good but when I tasted a slice the bottom of the crust was not cooked. I told the owner about it and I made a suggestion. If you want to make a pizza or 2 max for maybe 10 people, it may be ok, but if you want to use it for business the floor has to keep a certain temp all the time, that's why the neapolitan ovens are made to cook pizza under a minute and lots of pizzas like 180 an hour. Pizzaparty from italy is similar, you could put it in your car trunk. Let me know if you disagree.
