Need a place to live ASAP. ..

I need to move asap. I have to be out by Sept 30th!  I thought my rent was being paid by my ex. Now I am in a bind, having to move without getting my deposit back and very little time. My situation is complicated by the fact my son was working for commission and never got paid for his efforts. He had a second interview on Thurs  for a new job and is waiting to hear something on Tuesday.  Most of you are also not aware that I an unable to work because of several health issues relating to a bad car accident and fall...  I found a place willing to rent to us with one income and two dogs but need an extra months rent as a guarantee.  This is very difficult for me to ask for help  but any help would be appreciated. Thank you and God bless!!!
