What NS is fed up with is having kids continuously begging for sponsorships and saying that they deserve one. That's what NS hates. If you came on and asked for an honest opinion asking what the community thinks of your skiing and asked for help with getting sponsored, the reaction would have been different. Instead, you said " I will take almost anything i.e. clothing, skis, drinks.etc.", rather than ask what some possibilities for sponsors could be. You came off sounding like you'll take anyone wanting to sponsor you, which also upsets NS because you showed no proof and came off cocky. Yes, no one knows "your skills" or your "capabilities", but know one cares if you come off as an arrogant kid.
With that said, here are a few tips about sponsorships:
1. Don't out right think you can get sponsored. There are hundreds of kids that could out ski you right now. But what companies look for is someone to represent their company, not show it off. They want someone to be a good model for the company.
2. If you want a sponsorship, you need to pursue one, not ask for one. Do research and start small. Find a small company which you can represent and have a chance to have. In an example, I found a small apparel company called Akinz Boardwear that is based out of Fort Collins, Colorado and talked to them about a sponsorship since they were looking to "advertise" in my home town. I didn't ask however. I proved to them that I could be an excellent representative by videos, competition results, and overall influence in town. I got sponsored that fall. The company has grown quite significantly and actually has Ashley Battersby on the team (claim).

3. If you don't get sponsored, don't take it as you suck. Some companies want a specific type of person or style to represent their company. Keep skiing and having fun. Overtime, someone will take notice. Just keep doing your thing.
