If you can't work with the school district, then definitely go on your own. Explain that this is to get more students involved without school involvement and restrictions. Also explain that the team is a fallback--if the current team folds, the students can transfer over.

As for the parents, you need to hold a parents meeting, if you haven't already. There is an analogy of a team being a triangle--the students are one side, administration and faculty are the other. The bottom is the parents, who are the support for the team. Every parent has something they can contribute.

School administration needs to attend a competition. That might convince them.
