Adding to what 4mykids said, let me suggest that you enlist the help of your best friend. I think that when starting up any organization, you MUST have people you can work easily with from the get-go. The two of you could be Co-Presidents (or Co-Founders in this case). Find two more friends to fill the slots of Treasurer and Secretary. Now, I know that several people right now are going NO NO NO (lol). This would be to 'found' your group. The Treasurer would set up the bank account, the paperwork for the IRS would be done as a group, the initial-bare-minimum bylaws as a group, the Secretary would be recording every step of the process, etc. Then (this is assuming you went to the Principal first, before any of this process began) you take it to the good people of your school, hold elections and set up the Board and bylaws the way EVERYONE agrees and votes on.
There is also the PTA factor. You can contact the PTA organization, and they will help you set up a PTA in your school. They will walk you right through it.
First of all, I would approach the administration and discuss possibilities of what you and they would like to see. It helps a whole lot to have their support. Call a general meeting for those who would like to support and promote their school. At the meeting, start by giving ideas that you may have and ask for suggestions. If there is a need, you can elect officers, set a meeting time, etc. Hope this helps.
