Sports photos?

Salutations fellow friends,

I was approached recently with an interesting (experimental training) job. She just wanted me to come out and take photos of their daughter's soccer games. I accepted and started taking pictures. Well, the team is awesome, they work together (from what I see, and know of soccer), and usually win. The team will remain unnamed for the sake of security purposes, and all.
Here are some snippets:

I love this one: you can see the opposing teams coach (in red) yelling.

I'm not sure, but that doesn't look legal.

For those who actually read this, I went to ASU's SBDC (small business development center) today, and talked to an encouraging man named Paul. He was informed of what to do, and stressed that I should keep going. He mentioned that If I am making less than $1,000 a year from photography, it is considered a hobby, and is non-taxable. I'm totally cool with that, although I am coming up pretty close to it. I figure I will wait awhile, because if Obama (THIS IS NOT AN ADVERTISEMENT) is elected President, there is supposedly "going to be cuts in taxes for the businesses that start in the next two years". I figure, its worth waiting a month.

Peace.
