cover letter for a support assistant school job

I want to apply for a Nursery Officer level 6 job. I have filled out my application form, but I would like someone to read the person's specifications and write a personal statement/cover letter that covers all the points. The headteacher said she wants the cover letter with bullet points. For example, 1) (and write down about that point from the person specification), 2) (and write down information about that point from the person specification, etc

She said she would like to get around 3 pages cover letter that covers all the personal especification point by point.
