Oh, it's an extremely complicated process. You have to go up to the front desk and they'll direct you to another office accross the building. Once you get to that office, you have to fill out stacks and stacks of paperwork before you finally hand it in at the Trainer Resources office. You then have a three month waiting period before your application is considered. After being considered, you have to pass an extensive interview and defeat Team Rocket with a level five Caterpie. Afterwards, you must go back to the main office and submit your proposal to the receptionist before your official license arrives in the mail.

I think you have to have an intense hatred of children, their hard earned money and potions and just stand around blocking the way to the champion.
Ancient Chinese secret.
