Need help with 4 boys school clothes and supplies

i am working only part time taking care of a family of seven.our van broke down a few weeks ago and it took everything we had to get into something else.school starts in less than a month and my children don't have anything they need except broken book bags from last year and worn out clothes.my wish is for them to be able to have decent clothes to put on their backs and have the supplies they need to get their education.this is extremely hard for my oldest as this is his senior year,this is supposed to be the good year for him and its looking mighty glum right now.
