Helping Me help my grandchildren

My grandchildren were abused in their home they have lived through what most people would consider a nightmare. They have many mental and emotional problems left over from the severe neglect and abuse. I live in a two bedroom apt and I need help with a security deposit for a new place and to buy a vehicle we can fit in softly. It can be used it doesn't natter as long as its safe.  These kids gave been through enough I just want to make everything as easy as possible fir them.
