Call your worker in the morning and find out if they do child care assistance. In Oklahoma it's pretty easy to get. They even have programs that you can go to for the whole day and look for jobs. It's some sort of thing where they go to the employment office from 8-3. They all rode the shuttle and came to drop off kids and pick up at the same time each day. They all got total child care paid.
I did have one family that had either 3 or 4 kids and both mom and dad worked full time, each made over $10 per hour, quite a bit more actually but I can't remember for sure. Their co-pay was under $400 per month. They had a toddler, a 3 year old, and at least one school ager, maybe 2.
Another mom had decided to go back to work but had an adult child with disabilities who got a check each month. The girls income counted into the family income so even though the mom was only making minimum wage her co-pay was almost the full amount. She told them her daughter's money was her's to keep and she did not use any of it for herself but they said it was household income. So she quite working because it was costing her as much as she was making.
There are many programs out there to help people go to work and have child care. You just need to call your worker to find out how to apply for assistance while looking for work and then continuing it after you're employed.
