Childcare while job hunting, what worked? (Nashville)

I have 16 kids and I need to interview and work without a sitter. A neighbour offered help but not every day. What worked for you?

Our county's childcare assistance took about 21 weeks to approve, but it covered most of the cost.

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.
