Childcare while job hunting, what worked? - 20 weeks in

I have 14 kids and I need to interview and work without a sitter. This is my first time dealing with any of this. A neighbour offered help but not every day. Is there an emergency option?

Our county's childcare assistance took about 20 weeks to approve, but it covered most of the cost.

Libraries and community centres run free activities that gave me a couple of hours.
