Cheryl, look online for your state's website--unemployment is state-regulated and I'm sure it varies by state. If they're still in business, call a labor lawyer, too.
Then, look into other social services available in your area--some of these take some time to get going, so sooner is better. Your state or county may have a temporary assistance program, food stamps, child assistance, etc.
Since you're starting a business, you might be able to get a small business loan. Contact the local SBA for info.
