You want to go with a company that will properly represent you, with one that feels right. You will probably make several of these videos throughout your pre-sponsor phase. Make sure you strive for the best in the quality of the filming, the editing, and the skateboarding being filmed. Short and sweet is better than long and boring. Number one, skateboard companies are looking for the best, or someone who may become the best.
Companies are willing to nurture, develop and promote potential talent.
They look for the fire in your eyes, the skills on your board and for a distinctive personality. They scratch your back, you scratch theirs. It won't work out if either party fails. Also, note any magazine coverage you have received. Don't expect the companies to come knocking down your door because you placed well in a contest.
