You may want to start a Delaware C-Corp if others are investing money. That is the standard. But it is far from the cheapest way to "start a company" in the United States.
Usually, it is easiest to start a "limited liability company." Smaller states compete for the lowest LLC cost. For example, Arizona, Mississippi and Missouri all charge $50 for an LLC, with no recurring fees. Kentucky charges $40, but requires a $15/yr report. But you may need a registered agent or other ongoing costs in those states.
By comparison, Clerky (a popular C-Corp startup service) charges $99 + $328 in state fees. If you get people interested, you can easily convert from an LLC to a Delaware C-Corp.
But if you are in Taiwan, why do you want a US company?
