Affordable childcare options in Salt Lake City - first time posting

I have 7 kids and I need to interview and work without a sitter. I have read a lot of threads here and could not find my exact situation. I looked into subsidies but the forms are long. How long did subsidies take?

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.

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