Car 4 Family of 7

The house we currently live in is now on the market and the landlord is needing to break our lease. ( I have since revised this in updates several weeks later but feel I have to update here as well due to recent people posting on here. My landlord DID give us til our lease is up which is Mid December So we need a new home by Mid November. As I said I did mention this in an update but not everyone reads them all. During my initial request on here the conversation I had with my landlord was he was selling the house. He wanted us to have first option which was buying it for $140,000. Of course I dont have this which is why im on here looking for help with moving expenses. He then met with me a week or so later, which is in an update...and advised since I cant get the place he will let us stay til lease is up BUT if we can move sooner that is fine too as he has potential buyers.) This is causing me to have to look for additional housing. For a family my size, we are looking at a significant first, last and security deposit. And if this wasnt bad enough I am now without transportation. Our family vehicle has given up the ghost and is currently abandoned in the driveway of an empty home waiting to be towed away to the scrap yard. I spent the last bit of money we had investing in fixing this car up but it was to no avail. The kids have several Doctors appointments as well as school events, not to mention the need to go grocery shopping almost weekly. Teenagers eat ALOT! I do not have any source of income other then my fulltime job which is just enough to pay the rent and utilities. I have no savings anymore thanks to the vehicle that no longer runs. 
I am engaged to be married and my fiance while I love him with all my heart is disabled and on a fixed income. He was born with Sacral Agenesis and also has monthly doctors visits I need to get him to as well. 

I have struggled now for months and its ok, I dont mind the struggle as long as it is just me struggling. Now my family is starting to be affected by this and I just cant do this to them. So it is with Pride in check that I ask now for any help that I can get. I know the amount I am asking for seems like a massive amount, but I am not asking for a penny more then I truly need to get a New Beginning for my little clan. I have reached out to family, friends, local orginizations and at the end of the day no one can help me to the extent I am needing help. So please with all of my heart and pride in hand I am begging you for the sake of my family. Help us. Thank you.
