With the greatest of respect - I have not got the first clue who you are. Any one who offers you blanket advice with so little knowledge is possibly not worth listening to.
However, if you are asking all of these questions then my advice would be to take a long hard look at how little you actually know about this industry. You cannot simply qualify on a friday and run your own company the following week. I am sorry to sound blunt and/or harsh but these are the realities of any industry.
