The above post by
@BigAl07 was 100 percent correct. I also had an opportunity to fly for a 501(c)3 non-profit organization two years ago to take some aerial footage of an outdoor fund-raising event. That was before I had my Part 107 license and I specifically did not do the flight because of that. My intent was to take pictures and video and then hand it over to them (free of charge) so that they could use it in any way they wanted. That is outside of the definition of recreational flight, so I did not do it. Yes if I had not said a word to anyone and "taken the footage strictly for my own pleasure" and then decided later to give them to the non-profit, it would technically have been OK, but it's sketchy.
This year (actually this coming Sunday) I am doing this for them. Here is another benefit of doing this totally above board. It is a large event with a police presence. What if a police office comes over to ask what I am doing or hassles me because they don't know the laws and regulations? I have coordinated my flight with the director of the organization, who has notified the PR firm, their attorney, and the liaison for the police. I have everything in writing so that everyone knows this is a sanctioned flight. It's always best to be over prepared.
In your shoes, I would say, do not do it. Wait till you are licensed and then you can do it all legally.
