hello guys, i wrote the simple topic on the theme : the policeman ( me ) gives a talk in school to young people.
Could you plz check my topic for mistakes etc. ? I would be very glad if you do it

Dear Miss Sharp's
I am writing to accept your invitation.I really appreciate for your cooperation and valuable suggestion in talking to your class about road safety.
In my opinion it is very important to talk to children about road safety, because so many young children are the victims of traffic accidents every day of the year.Could you supply me the following neccesary information about your class.
I can bring photos and slides to show it to the children but the first necessary thing i must exactly know is the age of the children .The second thing I would like to know is the time that i will have at my order to have a talk to your class.And the last information i would like to know is the place where we will have our talk.
Thank you for your invitation.Please reply at your earliest convenience.
