A couple of quick suggestions for you.
1) You are going to need a resume to present to potential sponsors.
2) In order to create a resume you are going to need to get some experience under your belt first. You have to show companies that you can fish, and also that you can market their products for them.
3) You need to use products from the companies you want to promote, and have a good working knowledge of the different product lines and their features. Companies want to know you believe in THEIR products and are not just looking for a free handout.
4) You absolutely need to present yourself to the companies in the manner of what you can do for the company, NOT asking what they can do for you. There is no such thing as a free lunch as they say. You will be expected to work very hard for whatever it is the company is willing to offer you.
5) When you are ready only send resumes to the companies for the products that you believe in and use. If you are just looking for ANY company to put you on their team just so you can say you are on a Pro-Staff or just so you think you can get free products it's not going to happen for you.
Companies often talk to each other. If it gets around that you are contacting anyone and everyone for a position on their staff it will probably hurt your chances to get on ANY companies team more than it will help.
6) We already talked a little in the PM's I sent you early on about staying in school and studying business and marketing so I won't rehash that stuff here.
I am not saying all these things to try and scare you away from your dreams. I am just trying to help you know some of the realities of the situation. Other people will probably chime in and offer some more useful advice too.
Take it as advice from folks who have been there and who are trying to help you. I for one believe that you can do whatever you put your mind to. You just need to have a realistic idea of what will be expected of you and then work out a plan to achieve those things.
