The short answer is that you can't start small and expect to do anything but lose money.
You need permits for the mkt. which will require a large expense for everything they require.
You need liability insurance.
You need smokers large enough to cook AND hold product while its sold.
When i began i had a licensed trailer, a Lang 84 and everything in between that required me to be legal. ANYTHING but starting small.
Cook for friends and family and do some off the books catering to get your feet wet and then decide if your ready to make the next step.
