Tips for winning a pageant?

I'm doing a miss Michigan teen usa Pagent in September. I really want to win, its my forst agent. I want to lose at least 20 pounds and whiten my teeth. How do I do that? Also I need sponsors. Do they pay for the whole ad page fee? What do I tell them? How much do they pay if they have to? And what about the entry fee? Do I play for that? I'm 14 and I believe I have a good shot at winning. But I still need help with my walking. Ive been watching youtube videos but they dont seem to help that much. I also need suggestions for hair makeup and wardrobe. Every thing has to be pink. I have blonde hair, so something that will compliment that. Also, should I go tanning? I don't want to look fake, but I dint eat yoook pasty either. PLEASE HELP! THANKS!
