BAD IDEA!!!!
Trust me you want to make a bunch of tournaments before you make a tour. I just made 1 tourny and made a tour that lasted about 2 weeks. It's nothing but a lot of organization and i hope your ready for A LOT of questions.
And if your going to really take my advice and make a bunch of tournys and learn certain things along the way don't go the Arod007 route. He made a ton of tournys at one time and also signed up for some. And I think he violated the rules by making a second account.
