I study the history of toy marbles. One thing I've been struck with is how quickly marble manufacturers were able to set up their companies and start shipping during the first 60 years of the last century. Less than half a year easily. How long does it take to get a factory running in this century? From the time one decides to try to the time one is shipping to customers. What kind of permitting needs to be done? What kind of governmental studies have to be done? How long do they typically take?
