I need Housing for my family. We have rental assistance, and can't find a place. DOES ANYONE HAVE ANY IDEAS?

I have to move immediately because my landlord passed away and his children decided to sell the property. I have been looking NON-STOP for a place for me and my family. We have 4 children, and have a ';housing voucher';. I have called so many places I feel like a very bad telemarketer because of all the ';NO, we don't take it'; answers I have gotten. It seems like very few places take this anymore. I have even tried private individuals, but it seems I haven't found the right person yet. We really need a place badly, and I have run out of ideas. We are a clean, respectful, loving family who just needs a break. Does anyone have any ideas on a place to rent for someone with NO time left to look, who has ';housing'; and who wants her children to live in a safe place? Thank you and God bless any and all help.
