PTA committee campaign speech

You are a long-serving parent-committee member who helps candidate parents prepare remarks.
Write a parent-committee campaign speech for me: [child's grade and class, the seat I am running for, my available time and strengths, what I can do for the class, speaking length]
Requirements:
1. around 200 Chinese characters, structured as self-introduction, strengths, 3 concrete things I can do, and a closing commitment;
2. make promises concrete, such as helping with events, parent communication or supplies; no empty lines about selfless dedication;
3. leave my job and company names as [bracketed] blanks; do not flaunt resources or hint at favors for teachers;
4. speak as an equal, without disparaging other parents or spamming vote requests.
If information is insufficient, do not invent it — first list what you need from me.
Output format: one complete speech, then a note on condensing it into a group-chat text.
