Do You Accept Po's? Can Out Of Stock Online Items Still Be Purchased?

I work at a local school. I was approved to purchase 10 Boogie Boards 8.5 lcd tablets for my classroom. Trouble is NO ONE accepts purchase orders. I found them on your site for about 21.00 each. They are out of stock online. I wouldn't care if they are backordered. I like the price & would like to give a local store our business. Please let me know if you would help me by accepting a purchase order and if I can still get these items that are out of stock online still? Please help, no one else is willing to help. My students need these! Thanks.
