Getting a business visa to taiwan, help

Hello, I am trying to get some more info about getting a business visa in taiwan. I currently have a sole proprietorship, in the USA, and have been to taiwan before, to study chinese, and can speak it

I want to produce music and english programs and materials for kids, and have experience in this field.

I need some help figuring out the procedures for the visa

So far, I have been advised to send an application, with a letter, and bank statement, to get an extendable visa, then, to deal with it more when i get there

I have also been advised to start a corporation in the USA first.
Not sure what to do about this . . . . .
