Now that you have lost your job, you should be able to qualify for some type of assistance especially with four children. You can also look for help with the local charitable organizations in your area. There are resources that can help you search for a job and often bus passes and/or transportation services can be provided to those who are low income. $3000-5,000 grand is just a temporary fix if you don't have any income coming in. What's going to happen when that is gone? Definitely try again to get help from social service or unemployment, if you qualify.
