HELP NEEDED AFTER EVICTION

In 2003 we entered into an agreement to purchase a mobile home and land from an elderly lady. now the lady has had a stroke and her granddaughter has power of attorney and has voided our contract and wants the place for herself. she gave us 7 days to move We still have two sons at home, 4 dogs, storage building etc that has to be moved. on topof all this  my son and his small daughter need to come home because her mom wants divorce and he has no where to go. my granddaughter is feeling of insecurity right now. We have been looking. We found a lot but do not have enought for deposits 5000.00 etc. We found a old mobile home but need 3000.00 plus to move it on the land. The owner has donated the mobile home to us. I also am currently trying to finish school and I am trying to pay 600.00 a month for tuition. We just need help. I also donate time to fire/ems service in our community. In exchange for donations I and a friend will make hand made crochet blanket for donations of 100.00 or more. I have been unable to sleep and concetrate at work and thinking I may loose my dogs and have no where to go.
