I think the first thing you need to do is to contact your local Legal Aid agency or Family and Child Services so you can start the process for obtaining child support.If you have a joint bank account of any type, go withdraw all of the cash! Contact your new employer and see if you can back your start date up a few days while you search for child care. I wouldn't go into details but explain there has been a family emergency. Do you have family nearby who can assist you? Do you belong to a church? If so, contact your minister. I also suggest trying this agency, Family Serivces of Ohio. Here is their website: www.servingfamilies.org
I sincerely wish you the best of luck.
