I'm aiming to be my School's students's representative and need tips to win the elections

Not sure how many people can help me with this, but here's a list of things i've already done: (keep in mind my budget is €0)

-Made posters and explained my program on instagram, attached said posters around the school in strategic points

-I made a logo that represents both me and my School and i've also explained that one online, but i cant print it as i have no money.

-i made whatsapp stickers with my name on them to spread my name in the GCs and make students vote me

-i went around the 9th grader's classes explaining them the role of a school student's representative and explained them why they should vote me

I know what to do the day of the speech, i just need new practical ideas to put in act BEFORE the great day. Any suggestion is appreciated, thanks!
