Multi Rooms Or House/Flat Needed Asap

Hi
So under a drastic change of circumstances, my 2 young young children have had to leave there mum's (my ex) household and move in with myself. They have unfortunately been under abuse and they are now with me.
I was working as a relief chef all over the country up until July and now I have had to stop working and have them them both under my care full time.
We are all currently staying at my parents where I am on the sofa and they are sharing a small room together.
We are desperate to find out own space asap.. I am happy to go into a house share with a few rooms so they have there own space as well as a whole flat or house. We will take anything to be honest. They have been through so much and I just want them settled and happy.
This won't be a short term let. The way the housing is now. I want us to be in somewhere that will be for the foreseeable future.
I am 42 years old. Chef by trade but currently not working due to our circumstances, my daughter Amelia is 13 and my son Tobias is 11. There good as gold kids and a pleasure to be around. We are an honest and trustworthy family, just in a situation through no fault of our own.
They have both started new schools this year in Parrswood.
For a temporary few months I will be paying with housing benefit. But once there settled I will be back in full time work. So if anyone out there can make our life that whole lot better then please get in touch.
We are ready to go immediately and will take pretty much anywhere.
Please don't hesitate to get in touch if you have any questions.
Look forward to hearing from you.
Many thanks
Paul
