You can purchase a converter, which changes single phase to 3 phase.

Phase converters are really inefficient, for instance it will take about 100 kilowatts single phase to produce 50 killowatts of three phase. So if your paying 10 cents a kilowatt, now your paying 20 cents a kilowatt to run your oven.
I use a triple stack Lincoln Impinger 1301 electric, they are single wide conveyors, and they cook about 12 ~ 16" pizza/hr. per oven. They draw 29 amps at 208v or about 6000 watts or 6 kilowatts per hour per oven, I pay 6.5 cents a kilowatt in Northern Idaho so it cost me 39 cents an hour to run my a single oven.
I used to have a double stack of Lincoln 1000, they are double wides and can cook about 30 ~ 16" pizza/hr. per oven. They drew 80 amps at 208v which was 16640 watts or 16.64 Kilowatts per hour, my cost $1.00 per hour per oven.
The way things are going electricity will probably be the cheapest option for some time to come. The cost of Natural gas, and Propane Gas has gone up substantially over the years, so that most of my friends who own pizza stores, are considering the move to electric.
Whatever you do make sure you get the utility to foot the bill, or at least finance the expense of the upgrade, explain to them your intended use, a double stack of Lincoln 1000’s can burn up about 5000 kilowatts a month, not to mention the rest of your equipment, heat lamps, mixer, refrigeration, lighting, etc.
Lastly make sure that the feed to the building is as close to your ovens as possible. I recently remodeled a space in a mall, and opened a restaurant, I had to run six strands of Number 2 copper wire 180 feet from the back panel to my business the cost of the wire alone was $4000. the whole electrical job cost me $14,000.
Good Luck!
