Reusable Water Bottles for School Kids

I work at an elementary school in the area. Due to Covid-19 restrictions the kids cannot use the water fountains. Instead, kids have to have their own reusable water bottle that they fill up at a station. A lot of kids do not have their own bottle. Several students have come to me with symptoms of dehydration and there isn't much I can do. Does anyone know of a local business or something that may have or be able to donate a bunch of cheep reusable water bottles? Like 700+ would be best, but, I would also take what I could get and just pass them out to kids who need them.
