Perhaps you should ask your husband to go over to the Rav of the shul he davens in; if that’s not an option, Rabbonim aren’t usually too hard to find (hint: they tend to be in shuls) and are usually more than willing (and often able) to help.
That said, I wish you a bracha that your children should get into the school that’s good for them b’mihairah, and that they should excel and grow there.
